5. 11. W. G. Frith, Esq. Kulneah, Jessore. Also a collection of 

 sundries preserved in spirit : comprising two Bats, Kerivoula picta 

 (fine) and Nycticejus Temminckii ; — the following birds remarkable for 

 the locality — Gareulax squamatus, Iole virescens, and Hemixos 

 flayala, with the curious young of Centropus rufipennis, and those of 

 JNettapus coromandelianus ; of snakes — Bungarus annularis (small, 

 and bottled while in the act of swallowing a Tropidonotus stolatus), 

 Vipera Eussellii, Xenodon purpurascens (fine), the common Lyco- 

 don aulicus, Calamaria sagittata, and a remarkably beautiful specimen 

 of Dipsas trigonata, and the young of Hydrus striatus ; frogs — 

 Polypedates leucomystax (var.), Hyl.edactylus bivittatus (beauti- 

 fully marked variety), and an interesting series of the tadpoles of Sana 

 -fish— Syngnathus cunculus, B. Ham. ; and of insects — 



* In Dr. Cantor's ' Catalogue of the reptiles inhabiting the Malayan peninsula 

 and islands,' (/. A. S. XVI, 1060), R. rugulosa and R. vittigera, Weigraann, 

 are placed as synonymes of R. tigrina. This is a mistake. Neither of the 

 former appears ever to exceed in magnitude the British R. temporaria ; and R. 

 vittigera (v. ' R. assimilis, robi, passim), is readily distinguished at any age by its 

 semi-palmated hind-feet, the inter-digital membranes of which are not more deve- 

 loped than in our common Tree-frog (Polypedates leucomystax). In accord- 

 ance with thrs structure, it is decidedly less aquatic in its habits than the others 

 are, and is found further away from water, under shelter of low herbage and grow- 

 ing crops, where it can derive the necessary moisture from the night-dews. It is as 

 common as the great R. tigrina, in the vicinity of Calcutta. R. rugulosa = 

 R. Leschenanltii, D. and B. apud Cantor, sed nee apud Jerdon (at least Mr. 

 Jerdon sent to our museum a different and much larger species by that name many 

 years ago), v. R. bengalensis, Gray, apud nos (passim). We have not observed 

 this species wild, but have occasionally received a lot of living adults taken in the 

 neighbourhood. Some are distinctly marbled and variegated when alive, others 

 not so ; which is at variance with Dr. Cantor's statement. The pale dorsal line 

 seems never to occur in this species ; and is as often absent as present in R. vitti- 

 gera : but in R. tigrina it appears to be constant. Our largest male of R. 

 tigrina measures — head and body 7 in., and extended hind limb 9 in. Though 

 so common, we have never remarked the tadpoles of R, tigrina ; but the young 

 frogs, measuring — head and body but f in. to f in., are common. At any age, this 

 species is at once distinguished by its more gracile form, by the considerably less 

 obtuse shape of its muzzle, and by the brilliancy of its colouring when alive. Its 

 agility is remarkable ; often taking several long lapes in rapid and continuous 

 succession, making always for the water, and not plunging directly into it like R. 

 temporaria, but taking two or three successively diminishing springs along its 

 surface and then diving below. It is further remarkable for its extraordinary
