any hesitation. The Pinang variety, with the ordinary aspect of the 

 species, but with a purple chesnut colour on the parietes of the aper- 

 ture, confirms the opinion. 



Clausilia insignis, Gould. — The species sent under this name is very 

 distinct from the species from Malacca, which I have described in 

 MS. as C. stylus, and which I find in Mr. Cuming's collection 

 under the name of G. chinensis from Java. Possibly this name may 

 be intended for cochinchinensis, Philippi, the description of which I 

 have not seen, and which appears to be recognized as distinct by Pfeiffer, 

 from C. insignis, Gould. In May 1847, in referring to the Mergui 

 Clausilia philippiana, he says : " mit C. insignis, Gould, nahe ver- 

 wandt," a circumstance which, however, I cannot well understand, as 

 C. philippiana has only six whorls, and the specimen of insignis sent 

 has nine. Clausilia insignis differs altogether from C. stylus in its 

 smooth sculpture, its greater ventricosity, more blunted apex, the form 

 of the mouth and the number and disposition of the plicae in the 

 interior. 



Vitrina prcestans, Gould. Mr, Mason errs in saying that this is the 

 largest species of the Genus. In 1836 I described V. gigas y which is 

 1 ¥ 3 ^ inch in greatest diameter. 



Helicarion cassida, Hutton, described in 1838, is one inch two lines 

 in diameter, and an allied Abyssinian species equals it in size. 



Achatina octona. The shell alluded to under this name, or that of 

 octono'ides, is Achatina erecta, Benson, of the Chusan series. There is a 

 Bulimus octono'ides, Adams, belonging to the group to which B. graci- 

 lis, Hutton, belongs, a shell very nearly allied to Achatina erecta. 



The small red Pupa mellita, Gould, may possibly be P. bicolor, 

 Hutton, the animal of which, like many of the Mauritian Pupa, is yel- 

 lowish and vermilion. Pupa bicolor I have taken from Calcutta up to 

 the foot of the Himalaya in Rohilkhund, as well as at Galle in Ceylon , 

 and Dr. Cantor took it at Pulo Pinang.
