Mr. T. D. A. Cockerell’s Notes on Slugs . 
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 1 place them provisionally as a 
species, T. albida . Moquin-Tandon’s T. lialiotidea , 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 millim., breadth 18 millim., sole 5^ millim. 
broad. 
Finely granulate above, blunt-squarish behind. Above 
dull oclirey, 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 occidentalis (Guild.) are different forms of 
the same species *? 
Hgalimax ( Jarava ) andamanicus ) Godw.-Aust. 
A specimen in the British Museum, which appears to be 
typical, is labelled u Andaman Is., Dr. J. Anderson.” It 
has the mantle strongly convex; the colour is yellowish 
white, without markings ; foot slightly orange-tinged. 
Hgalimax andamanicuSj var. punctulatus , 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 I was not able to sufficiently 
examine it. It seemed to me that it had some sort of central
