II. On some und escribed species of Camptoceras, and other land- 

 shells, by H. F. Blanford, Esq. 



In addition to the only known species of the interesting genus 

 Camptoceras (C. tcrebra, Bens.), Mr. Blanford describes two others, 

 lately discovered by Major Godwin- Austen in the Mymensingh j heels. 

 Besides these the author describes one Alycosus, one Diplommatina, 

 two Glessulce and two species of Helicarion, all from Darjeeling. 



III. On some new or imperfectly knoivn Indian Plants, by S. 

 Kurz, Esq. 



This is a continuation of Mr. Kurz's very valuable notes on 

 various Indian plants (including those from Burma and the Malay 

 Archipelago), published in our Journal for this year. The present 

 paper contains a large number of new species described from 

 Burma, chiefly from the collection of Dr. Brandis. 



IV. Note on Onchidium verruculatum, Cuv., from Ceylon, by 

 H. Nevill, Esq., C. S., Ceylon. 



Animal ovoid, thick, solid, roughly tuberculated, especially down 

 the centre of the back ; tubercles irregular, very retractile ; dotted 

 at times with cells or points ; sometimes elevated, containing a black 

 matter, occasionally dendritically filamented on the posterior slope. 



Mantle, above, dark olive, rough, thickened ; beneath, yellowish 

 at the outer edge, shading into dark olive grey at the junction with 

 the foot. Foot pale greenish white, soft, semi-pellucid. Ten- 

 tacles grey ; head and its appendages very dark above. 



Length 2 inches, breadth 1£ inches, height in centre 1 inch. 



This species was originally described and figured in Napoleon's 

 ' Expedition to Egypt' under the name of Onchidium Peronii, a Mau- 

 ritian species. Cuvier subsequently called the Eed sea form 0. ver- 

 ruculatum, and it is interesting to find it in Ceylon. 



It has been considered to represent one of the typical species of 

 Peronia, but it has afforded a singular confirmation of the views 

 expressed by Dr. Stoliczka in the Journ. As. Soc. Beng. Vol. 

 XXXVIII, Part II, No. II, 1869, where, after an account of the 

 anatomy of the genus, he proceeds, (page 99.) to show the probable 

 identity of the so-called genera Onchidium, Onchidiella, and Peronia 



It would appear from the evidence brought forward there, that 

 the only true grounds for separation of Onchidium and Peronia
