Mr. W. H. Benson on new Asiatic species of the genus Pupa. 127 



dantly one year, I could not obtain a specimen at the same season 

 in the following year. 



4. Pupa brevicostis, nobis, 



T. rimato-perforata, cylindraceo-ovata, cornea, apice obtuso ; anfrac- 

 tibus 4y, longitudine celeriter crescentibus ; ultimo antice non 

 ascendente, ^ longitudinis testae sequante, superioribus convexis, 

 superne remote semicostulatis, ultimo et penultimo subplanulatis, 

 dimidioque inferiori cseterorum sericeis, muticis ; apertura rotun- 

 dato-ovata, 5-6-plicata ; plica 1 angulari, brevi ; secunda parietali 

 profundiore, obliqua ; columellari unica ; palatalibus 2-3 pro- 

 fundis ; peristomate expanso, subreflexo. 



Long. 1^ mill., lat. vix 1 mill. 



Hah. ad Barrackpore, Bengal. 



Taken by Dr. J. F. Bacon on the trunk of a tamarind-tree at 

 the Cantonment of Barrackpore, near Calcutta, during the rainy 

 season of 1848. Out of several individuals forwarded to me, 

 overland, by letter in a quill, two reached me alive, and creeping 

 about w^hen supplied with moisture enabled me to verify their 

 affinities. The lower pair of tentacula is deficient or inconspi- 

 cuous, as in Vertigo ; the upper pair carry the eyes at their sum- 

 mits. The shell is often carried at an angle of 45°. 



In 1834 Captain Hutton referred a small shell to the genus 

 under the name of Pupa canopicta, which belongs strictly to Bu- 

 limus, as conjectured by Pfeiffer, ' Monogr.^ vol. ii. p. 82. It is 

 figured, no. 492, in that genus by Reeve. It is necessary to re- 

 mark that in the numerous specimens which I have examined, 

 the callous parietal tooth at the junction of the outer lip has 

 never been wanting. Yet this character was omitted by Captain 

 Hutton, and it is not noted either in Reeve^s figure or descrip- 

 tion. I first took the shell in Bundelkhund in 1826; specimens 

 received in 1835 from Captain Hutton showed how the tubercle 

 had been overlooked by him, the shells being still covered by the 

 dirt, from the presence of which he had named them. Subse- 

 quently I found the species abundant under stones and rocks at 

 Delhi, and Dr. Bacon met with it in great profusion at Kurnal 

 on mud-walls and under tiles. It has never occurred to me or 

 to my correspondents on the left bank of the Jumna nor of the 

 Ganges. Dr. Bacon found a specimen or two at Dinapore on the 

 right bank of the latter river, so that it has an extensive range 

 to the south and west of those streams. 



The only locality hitherto given for the sinistral toothed Pupa 

 Pottebergensisj Krauss, from Southern Africa, is the Pottenberg 

 Mountain in Zwellendam, where Krauss found it, though rarely, 

 on plants. Sir Edward Belcher pointed the shell out to me as 

 occurring near the Bound Battery in Simon^s Bay, among Me-
