Mr. T. D. A. Cockerell's Notes on Slugs. 389 



these white specimens are more than a varietal form of halio- 

 tidea or some allied species ; but as they do not agree exactly 

 with anything known to me I place them provisionally as a 

 species, T, albida. Moquin-'i andon's T. haliotidea^ var. 

 albinos^ does not appear to be identical with the Spanish 

 albida. 



The type specimen of albida is now in the British Museum. 



Vaginula olivacea (Stearns). 

 Veronicella olivacea, Stearns, Proc. Bost. Soc. Nat. Hist. 1871. 



Length 45 raillim., breadth 18 millim., sole 5^ millira. 

 broad. 



Finely granulate above, blunt-squarish behind. Above 

 dull ochrey, indistinctly and minutely marbled with grey ; a 

 pale dorsal line is slightly indicated on posterior half. Supe- 

 rior tentacles (eye-peduncles) bluish grey ; inferior tentacles 

 pale ochrey, concolorous with head and underside of body. 

 Jaw brown ; I counted about eighteen ribs without removing 

 it from the animal. 



Described from a specimen sent to me by Mr. W. G. 

 Binney, collected in Nicaragua. The Californian locality 

 quoted for this species is surely rather doubtful ; probably the 

 specimen found was accidentally introduced. Is it not possible 

 that olivacea and occideatalis (Guild.) are different forms oi 

 the same species '? 



Hyalimax (Jarava) andamanicus, Godvv.-Aust. 



A specimen in the British Museum, which appears to be 

 typical, is labelled " Andaman Is., Dr. J. Anderson." It 

 has the mantle strongly convex ; the colour is yellowish 

 white, without markings ; foot slightly orange-tinged. 



Hyalimax andamanicuSj var. punctulatuSj var. nov. 



Yellowish white ; foot slightly orange-tinged. Minute 

 grey specks on mantle and grey streaks on hind part of body. 



Hab. Andaman Islands {Dr. J. Anderson] Brit. Mus., in 

 bottle with type). 



The mantle of this specimen is flattish, so that the outline 

 of the slug is greatly depressed compared with the typical 

 one. The jaw does not seem quite like that figured by God- 

 win-Austen for the type : but 1 was not able to sufficiently 

 examine it. It seemed to me that it had some sort of central
