claw (which in three specimens sent is on the dexter side) are armed at 

 the middle (typically) each with an enormous tooth. In the other variety 

 the claws are unequal in the male (the left being rather the larger in the spe- 

 cimen sent), and quite equal in the female, — in both sexes much exceed- 

 ing in size the small claw of the male of the other variety. There is also 

 a marked difference in the colouring of the claws ; those of the second 

 variety being weaker in hue, — whence not improbably the whole difference 

 may depend on the latter having cast and renewed the organ. In Gela- 

 simus and other Crabs with very unequal claws, the big one is as often on 

 the right side as on the left. From the size and seeming abundance of 

 this fine land-Crab, it is probably much eaten by the Andamaners. 



A fresh-water species sent is the female of a new genus akin to Varu- 

 na, remarkable for the small size and nearly round form of the last arti- 

 culation to the tail, which is placed within a notch of the penultimate 

 articulation, that accordingly half surrounds it, and is the largest of 

 the series. 



Other species of Crabs sent are a new Zozymus (since received also 

 from Ceylon), Eriphia tuberculata, nobis, n. s. (common on the Bur- 

 mese coasts), Trapeza ferruginea (? Latr.), Pilumjstus vespertilio, 



GRAPSUS STRIGOSUS, GR. MESSOR, SESARMA TETRAGONA, CiENOBITA RU- 



gosa, C. , a Pagurus, and Gonodactylus chiragra of the Squil- 



la group. 



A species of Scorpion and Scolopendra morsitans are also sent ; and 

 of Badiata a species of Comatula, two of Ophiocoma, one of Echinus, 

 a Holothuria, and a Sirinx (?). Several interesting forms likewise of 

 Annelides. 



2. E. F. Kelaart, Esq., M. D., Trincomali. To this gentleman we are 

 indebted for a very interesting series of marine Crabs, amounting to 15 

 species, with specimens of Ophiocoma, Ophiura, Ukaster, Asterina, 

 &c. Also a Filaria from the ovaries of the Pearl Oyster. 



3. I have next to announce the presentation of a large collection of 

 stuffed specimens, from his highness the Maharaja of Burdwan. This 

 collection contains numerous duplicates, and some very acceptable spe- 

 cimens — especially one or more undescribed species of mammalia, so lar as 

 I have been able to discover. 



Of Quadrumann, adult male and female of the Mandrill (Papio mai- 

 mon), and a young male of the Drill (P. leucoph.eus), — well set up : a 

 Monkey, also, which I take to be the Inuus assamensis (v. pelops) ; and 

 other species with which we have long been well supplied. Two kinds of 

 Lemur are sent ; one the L. albifrons, Geoffroy ; and the other is pro- 

 bably —
