Proserpina pisum. Shell globular : pale yellow and whitish : 

 smooth and shining: apex very obtuse: spire ^vvell elevated, with 

 very convex outlines : whorls five, quite convex, with the suture not 

 impressed : last whorl very large and high : aperture longitudinally 

 lunate : labrum sharp, moderately thickened within, without teeth 

 or lamellae : columella moderately produced nearly in the direction 

 of the axis of the shell, with one sharp prominent nearly transverse 

 plait: labium with a very prominent and sharp revolving plait near 

 the columella. 



Mean divergence about 110^ ; length of aperture .15 inch ; total 

 length .21 inch ; greatest breadth .24 inch ; least breadth .2 inch. 



For this elegant species of Proserpina, and several of the above 

 species, I am indebted to my friend. Rev. F. R. Holland, who has 

 collected them in person ; and, as on previous occasions, has libe- 

 rally shared with me the results of his labors. 



Additional specimens of Helix ingens, from Mr. Chitty and from 

 Miss Agnes Hines, show that the umbilicus, although so remarkable 

 in the specimen originally described, is often wanting ! A highly 

 colored specimen sent by Miss H. is, for both size and beauty, the 

 most superb of all the land shells of Jamaica. 



By the kindness of ]Mr. Bland, I am furnished with specimens of 

 the elegant Cijclostoma Sauliae Soich., from Worthy Park, St. John's, 

 Jamaica. C. suturale Soiob., like most of the shells, which are as- 

 cribed to Demarara on the authority of Mr. Bainbridge, belongs to 

 Jamaica. 



^p^ Tn reply to an inquiry respecting the distribution of the ter- 

 restrial shells of the Philippine Islands, Mr. Cuming says, " T did 

 not find more than ten species the same in different islands, at which 

 I was much surprised." The general results of Mr. Cuming's re- 

 searches, in relation to the distribution of the species, marine, fluvi- 

 atile, and terrestrial, of the shells of these islands, would be a most 

 interesting and valuable contribution to science.
