that of habit as shown by one only of them extending its range to the Gange- 

 tic delta, superadded to the slight though constant differences of colouring 

 (alike in Sc. tristriatus from the jungles N. W. of Midnapore to Ceylon), 

 indicate the extreme caution necessary ere we conclude other allied races to 

 be merely varieties of the same, from their general similarity of size and 

 colouring. — N. B. The Palm Squirrel of Pennant's ' Quadrupeds' (II, 415), 

 from Ceylon, with "an obscure pale yellow stripe on the middle of the back," 

 &c, may perhaps prove to be a third allied species of this subgroup, and 

 there may be others yet undiscriminated. 



Other species have a black medial dorsal line, as the two next which are 

 closely allied, and have conspicuous small white-tipped pencil-tufts to the 

 ears. 



19. Sc. McClcllandii, Horsfield, P. Z. S. 1839, p. 152 : Sc. Pembertonii, 

 nobis, J. A. S. XI, 887. Inhabits Sikim, Bootan, and the hill ranges of 

 Upper Assam. Two specimens from Darjeeling ; presented by the late Mr. 

 Webb and Mrs. Oakes. This diminutive species has a deep black median 

 dorsal streak, and two much less conspicuous brown lateral streaks, divided 

 from the former by dull pale streaks of the same breadth with the last, and 

 beyond the lateral dark streak is one of an albescent-buff colour : tail 

 margined behind nearly as in Sc. lokriah, or rufous subterminated with black, 

 and tipped with brownish-buff. 



20. Sc. Barbel, nobis, n. s. (PI. XXXVI, fig. 3). Resembles the last in size 

 and structure, but is much more vividly coloured. There are five distinct 

 black bands, three of equal length and breadth, the outermost less developed ; 

 alternating with four rusty-whitish bands, of which the two outer are rather 

 brighter than the two inner, and are continued forward to the moustaches, 

 passing beneath the eye : under-parts and inside of limbs bright pale ferru- 

 ginous : the tail margined behind as in the preceding species, or rufous, each 

 hair subterminated with black, but tipped with white. Three specimens, from 

 the Tenasserim province of Ye, presented by the Rev. J. Barbe. 



The next would seem to form an analogous little subgroup with Sc. in- 

 signis, Horsf., of Sumatra and Java. 



21. Sc. sublineatus, Waterhouse, P. Z. S. 1838, p. 19: Sc. Delesserti, 

 Guerin, Mag. Zool. 1842, and Zoologie du Voyage de 31. Ad. Delessert, where 

 figured. Inhabits the Nilgherries. Specimen presented by T. C. Jerdon, Esq. 

 This minute Squirrel has remarkably dense close fur (as described of Sc. 

 insignis), of a dark grizzled olive-colour, tinged with tawney, and having 

 three pale lines alternating with four dark ones on the back and croup ; the 

 outer dark lines narrower and somewhat less dark than the others. It has 

 thus the median line pale, as in Sc. palmarum and Sc. tristriatus j whereas 

 Sc. insignis is described to have the median line dark (but this, I suspect, needs 

 confirmation) : under-parts dull tawney : the tail grizzled dusky and ferru- 

 ginous. 



22. Sc. vulgaris, Lin. Specimens in summer and winter pelage, presented 

 by Mr. Bartlett and by the Cornish Institution. Inhabits Europe and 

 Northern Asia. 



23. Sc. hudsonius, Pallas. N. America. Presented by Mr. Bartlett. 

 Finally, of the Marmots, we possess — 



Arctomys bobac, Schreber : Mus arctomys, Pallas : Arct. himalayanus and 

 A. tibetanus, Hodgson, J. A. S. X, 777, and XII, 409. Adult and young 

 (not in good condition), the former presented by Capt. Huddleston, who 

 brought it from Almorah ; the latter procured near Darjeeling by the late 

 Mr. Webb : and a living young one, now more than half grown, presented 

 by G. A. Bushby, Esq., as noticed in p. 385 ante. This little animal con- 

 tinues in perfect health and vigour, and has only now (in the middle of July)
