4. A small collection from Major Berdmore, sent by him from the 

 Sitang valley, Pegu. It consists chiefly of species previously forwarded 

 by that officer ; though several of them are still highly acceptable. Of 

 mammalia, Rhinolophus affinis, Horsfield, — Sorex fuliginosus, nobis 

 (J. A. S. XXIV, 362), and Sciuroptera sagitta apud nos (J. A. S. 

 XXIII, 731A Of birds, a fine pair of Buceros cavatus. Of reptiles 

 and fishes, a few known species, including a small Mastacembalus 4 in. 

 in length, which seems to be M. unicolor, K. and V. H., but with 

 37 dorsal spines (instead of 34), and a row of black spots along the soft 

 dorsal and more obscurely along the anal.* Also a few Crustacea and 

 some good insects.f 



We have another Mastacembalus from Maulmein, which seems to be 

 undescribed, and may therefore be designated — 



M. zebrinus, nobis. Tail detached from the dorsal and anal fins, as 

 in the common M. pancalus of Bengal. Series of 28 or 29 dorsal spines. 

 Colour pale brown, deeper along the back ; and marked throughout 

 (more distinctly in the young) with dusky transverse stripes, alternating 

 with fainter stripes more or less regular, which latter are often double or 

 more or less divided, and are set off by the narrow pale interspaces,— much 

 as in the ' Dauw' or original Zebra (Equus Burchellii). In the larger 

 specimens the stripes are more or less obsolete, except towards the tail. 

 Dorsal and caudal fins minutely striated ; the anal with broad stripes, as 

 on the sides. Our largest specimen, apparently full grown from its bulk, 

 is 8| in. in length. 



We have also a small Siluroid fish from the same locality, which 

 appears to be new both as regards genus and species. 



Amblyceps, nobis, n. g. Affined to Olyra,J McClelland, but the head 

 much broader and flatter, with minute eyes, placed near the hind aperture 

 of the nostrils : two pairs of cirri above and below, the inner above 

 situate between the fore and hind apertures of the nostrils : pectoral and 

 dorsal spines short and concealed, but comparatively robust : the second 

 or adipose dorsal short and low ; and the ventrals and anal also short : 

 tail large and moderately furcate : a band of card-like teeth above and 



* The Emts formerly sent by Major Berdmore, and referred to E. ocellata, 

 Dumeril and Bibron (J. A. S. XXII, 645), proves to be totally distinct from the 

 latter, of which I have lately obtained two living specimens in the Calcutta bazar. 

 The Burmese Terrapin may therefore now bear the name E. Berdmorei, nobis. 



f Another, 9^ in. long, since received, has 36 dorsal spines, including the 

 comparatively large one immediately anterior to the soft-rayed dorsal. 



X This name is pre-occupied in Botany.
