166 PEOCEEBINGS OF THE MALACOIOGICAL SOCIETY. 



Museum, South Kensington. These latter must, I think, include 

 Gray's types, as the Museum possesses his collection. 



The four last species are very closely allied, and in my opinion only 

 forms of one variable species. I should not even make varieties 

 of them. 



31. Glessula SERENA (Benson). 

 Achatina serena, Bens. : Ann. & Mag. Nat. Hist., vol. v (1860), 

 p. 384. 



JIab. — Ceylon. 



Nearly allied to Ceylanica. 



32. Glessula subsekena, n.sp. PI. XY, Figs. 7, la. 



Testa ovato-turrita, solidiuscula, politissima, obsolete striatula, 

 fulvo-cornea, pellucida ; spira subturrita, apice obtusato ; sutura 

 impressa, marginata, crenulata ; anfractus 7 planiusculi, ultimus 

 ^ longitudinis vix sequans ; apertura semi-ovalis ; columella valde 

 arcuata, albido-callosa, marginibus callo junctis, ad basin abrupta et 

 oblique truncata. Long. 22, diam. 11mm.; apertura 10 mm. longa, 

 5 lata. 



Sab. — Peermede (Travancore) and Anamallays. 



The last whorl is longer, and the spire less elevated than in the 

 Ceylonese serena, and the whorls, especially the upper ones, are less 

 convex. 



33. Glessula Desha yesi (Pfeiffer). 

 Achatina Deshayesi, Pfr. : Mon. Hel., vol. iii, p. 495. 

 Hab. — Ceylon. 

 Like a very small nitens with a shorter spire. 



34. Glessula pachtcheila (Benson). 

 Achatina pachycheila, Bens. : Ann. & Mag. Nat. Hist., vol. xii, 

 (1853), p. 14. 

 Bab. — Ceylon. 



According to Benson's types in the Cambridge Museum, this species 

 is a narrower shell than the last. The two species are, however, 

 closely allied, and often confused in collections.

 Achatina pyramis, Bens.: Ann. & Mag. Nat. Hist., vol. v (1860), 

 p. 463.
