Part 22 (1/2)

_The Black Pigmy-Shrew_.

HABITAT.--Khasia hills.

DESCRIPTION.--”Very dark colour, extending over the feet and tail which is even _blackish underneath_; fur blackish-brown above, a little tinged rufescent, and with dark greyish underneath; the feet and tail conspicuously furred, beside the scattered long hairs upon the latter.”--_Blyth_.

This species was determined by Blyth on a single specimen, which was found without its head, impaled by some shrike upon a thorn at Cherrapunji. The same thing occasionally occurs in England, when the common shrew may be found impaled by the rufous-backed shrike (_Lanius collurio_).

_SUB-GENUS SORICULUS_ (_Blyth_).

The foregoing species being of the _white-toothed_ variety (with the exception of _S. melanodon_, which, however, exhibits coloration decidedly the _reverse_ of the following type), we now come to the shrews with teeth tipped with a darker colour; the dent.i.tion is as in the restricted shrews, with the peculiarity of colour above mentioned. The hind feet of ordinary proportions, unadapted for aquatic habits, and the tail slender and tapering, like that of a mouse, instead of being cylindrical with a stiff brush at the end.

NO. 145. SORICULUS NIGRESCENS.

_The Mouse-tailed Shrew_ (_Jerdon's No. 82_).

HABITAT.--Sikim and Nepal.

DESCRIPTION.--”Above dark-blackish or blackish-brown, slightly tinged rufescent, and with a silvery cast in certain lights; beneath greyish-black” (_Jerdon_). Feet and claws pale; tail slender, straight and naked.

SIZE.--Head and body, 3-1/4 inches; tail, 1-1/2 inch; hind foot, 5/8 inch.

Jerdon says that Kellaart named an allied species from Ceylon _Corsira newera ellia_, but I have not been able to find it in his 'Prodromus Faunae Zeylanicae,' nor elsewhere.

_GENUS CROSSOPUS_ (_Wagner_).

The hind feet large; the lower surface, as also of the tail, fringed with stiff hairs; tail somewhat compressed towards the tip; habits aquatic.

NO. 146. CROSSOPUS HIMALAICUS.

_The Himalayan Water-Shrew_ (_Jerdon's No. 83_).

NATIVE NAMES.--_Oong lagniyu_, Lepcha; _Choopitsi_, Bhot.

HABITAT.--Darjeeling.

DESCRIPTION.--Fur dark brown above, paler beneath; rusty brown on the lower part of throat and middle of belly, according to Jerdon; slate coloured back with scattered long hairs, which are longer and white-tipped on the sides and rump, according to Blyth's memoir; ears very small, hairy, concealed; tail long, slender, fringed with stiff whitish hair beneath; whiskers long and brown.

SIZE.--Head and body, 5 to 6 inches; tail about 3-1/2 inches; hind foot, 3/4 to 11/12 inch.

Jerdon procured this water-shrew at Darjeeling in the Little Rungeet river; it is said to live on small fish, tadpoles, water insects, &c. The movements of the English water-shrew, when swimming, are very agile. It propels itself by alternate strokes of its hind feet, but with an undulating motion, its sides being in a manner extended, and body flattened, showing a narrow white border on each side; then the fur collects a ma.s.s of tiny air bubbles which make the submerged portion glow like silver. It prefers clear still water, but at the same time will make its way up running streams and ditches, and occasionally wanders away into fields, and has been found in houses and barns.

Its food is princ.i.p.ally aquatic insects, worms, mollusca, and freshwater crustacea. In Bell's 'British Quadrupeds' its mode of poking about amongst stones in search of fresh-water shrimps (_Gammarus pulex_) is well described. Mr. F. Buckland states that he once dissected a water-shrew and found the intestines to contain a dark fluid pulpy matter, which, on being examined by a microscope, proved to consist entirely of the h.o.r.n.y cases and legs of minute water insects. Continental writers declare that it will attack any small animal that comes in its way, giving it quite a ferocious character, and it is said to destroy fish sp.a.w.n. I can hardly believe in its destroying large fish by eating out their brain and eyes. Brehm, who gives it credit for this, must have been mistaken. I have also read of its attacking a rat in a trap which was dead, and was discovered devouring it, having succeeded in making a small hole through the skin.

In England this animal breeds in May. The young are from five to seven in number, and are brought forth in a small chamber in the bank, which is constructed with several openings, one of which is usually under the level of the water.

Dr. Anderson has very fully described the Himalayan species under the name of _Chimarrogale Himalaica_. He caught a specimen in a mountain stream at Ponsee in the Kakhyen hills, 3500 feet above the sea level, and observed it running over the stones in the bed of the stream and plunging freely into the water hunting for insects.
