nued over the spine and along the upper margin of the first dorsal fin, upon 

 which it gradually diminishes till it disappears at the extremity of the fin ; a 

 similar ridge commences gradually behind the first dorsal, and in like manner 

 ascends and gradually disappears towards the tip of the second dorsal fin : a 

 strongly marked lateral ridge commences gradually, near and a little posterior 

 to the abrupt commencement of the medial dorsal ridge, diverging from that 

 slightly till it reaches as far as the posterior base of the first dorsal fin, then 

 continuing parallel to the back, and expanding at the tail so as to merge and 

 disappear among the scales of that organ, which are similarly enlarged : a se- 

 cond and less prominent lateral ridge appears about half-way down the side, 

 scarcely traceable for some distance above and posterior to the pectoral fins ; 

 this continues parallel to the upper lateral ridge, and in like manner becomes 

 diffused over and disappears upon the tail : lastly, another ridge appears a little 

 behind the pectorals and is continued along the anterior margin of the ventrals; 

 another again is continued along the anal fin; and there is a lateral ventral ridge, 

 commencing gradually from near the posterior base of each ventral fin. All 

 the scales are conspicuously carinated. The general colour is brown, spotted 

 all over on the upper surface with moderately large but unequally-sized black 

 spots, placed nearly in rows both longitudinally and transversely : these spots 

 are smaller on the head, and disappear anteriorly to the eyes, being also 

 comparatively indistinct on the two dorsal and the anal fins : the lower parts 

 are spotless throughout. The spots and the ridges are exhibited in the 

 accompanying plate, and also a portion of the upper lateral ridge (fig. 1, a), 

 parallel to the commencement of the anterior dorsal fin, natural size, and 

 the same magnified (b). Length of the specimen nearly 4 feet. The second 

 figure in the plate represents an Australian species of true Scyllium, the Squa- 

 lus ocellatus of Gmelin. 



6. From our Librarian, Baboo Rajendralal Mittra, — The fresh laid egg of 

 a Cassoway (Cassuarius emeu.) 



7. From E. Lindstedt, Esq. — Some fine fresh specimens of sundry Snakes. 



8. By R. W. G. Frith, Esq., I have been kindly permitted to select 

 such specimens as were required for the museum of an extensive collection of 

 mammalia and birds, chiefly procured in the vicinity of Malacca. The only 

 species quite new to the museum are two birds — an Accipiter, which seems 

 to be undescribed, and Brachyurus cceruleus, (Raffles, v. Pitta gigas, Tern.), 

 — and one fish — Osphronemus olfax, Cuv. and Val., Hist. Poiss. VII, 282 : 

 but various other highly interesting specimens have also been selected, tend- 

 ing to complete our series of Hylobates lar, Presbytis obscurus and Pr. albo- 

 cinereus, (Desm.), Galeopithecus Temminckii, Paradoxurus leucomystax (apud 

 Cantor),* Lutra(Aonyx) barang, and Rhizomys sumatrensis, among mammalia : 



* I differ from Dr. C. in considering this species to be P. leucomystax of Gray, from 

 recollection of the original specimen in the Zoological Society's Garden, upon which 

 the name was founded.
