form which has been called Helix discrepans by Pfeiffer. The abbe 

 A. Vathelet found a clear corneous race in one locality, though where 

 I do not know ; and this is what I named var. corneiis. 

 Common under stones at Bailey Bay. — (Cook.) 



Zonitoid.es minusculus (Binn.). 



' Plate LXII, Figure 17. 



A number of specimens collected by Prof. Verrill's party show 

 some variation in the size of the umbilicus, as in those from Florida; 

 and in some it is quite as wide as in the form called var. alachuanus 

 by Dall. Some specimens before me were taken many years ago by 

 Prime, and it is probably to be reckoned as indigenous. It is a com- 

 mon and wide-spread North American and West Indian species. 



Common in the yard of a house at Bailey Bay, under stones.

Family LIMACIDiE. 

 Xiimax flavus L. 



Typical specimens of this European species were taken by Prof. 

 Verrill's party. It is not uncommon in Philadelphia and some other 

 Eastern cities, but has not hitherto been reported from Bermuda. 



Under stones. Also taken at night, by lantern light, on stone 

 fences.— (A. E. V.) 



Agriolimax Isevis (Miill.). 



Cockerell, Journ. of Malacol, vi, p. 3 (1897). 



A young specimen was found by Prof. Cockerell among Ainalia 

 gagates collected by the naturalists of the ' Challenger' in 1873, and 

 is now in the British Museum. 



Am.alia gagates (Drap.). 



E. A. Smith, Proc. Zool. Soc, Load., 1884, p. 276. Cockerell, Ann. Mag. N. H. (6), 

 vii, p. 328 (1891). 



Taken by the ' Challenger ' naturalists in 18V3, by Mr. T. H. Aldrich 

 in 1889, and by Prof. Verrill in 1898. It would therefore seem to 

 be firmly established in Bermuda. Easily known by the very dark 

 color and keeled back. 



Found at night creeping on the stone fences. Taken while hunt- 

 ing snails Avith a lantern. Occasionally found under stones. —
