Specimen No. 60,964. Another specimen. 



Of this slug two specimens are before me : one (the type) in the 

 collection of the Academy, the other belonging to Miss Mary A. 

 Schively. They were collected in the Public Garden at St. George, 

 Bermuda, in July, 1888. The more prominent external characters 

 are the large size, dark, mottled coloration, and rather unusual 

 nearness of the genital opening to the sole. One of the specimens 

 is but slightly curved, the other is decidedly curved toward the 

 ventral side ; both are nearly flat below. 



There may be some doubt entertained as to the origin of Vagin- 

 nhis in Bermuda. The lists of Bland and others show the snail- 

 fauna of the island to consist of three elements, viz. : indigenous or 

 peculiar forms,' forms introduced by natural means from the West 



1 This includes only the genus Poecilozonites with four species and a dumber 

 of varieties. See Pilsbry, in Proc. Acad, Nat. Sci. Phila. 1888, p. 285.
