﻿44-6 SMITHSONIAN MISCELLANEOUS COLLECTIONS [VOL. 47 



The young cover the shell to a greater or less extent with pellets 

 of their own faeces. 

 Veronicella schivelya var. bahamensis now PI. lix, fig. i. 



Near Johnson's place, Nassau, and on Little Abaco, at Nield's 

 place. 



This large Veronicella, while not agreeing in all particulars with 

 Dr. Pilsbry's account of the Bermuda species, is evidently closelv 

 allied to it. 



The young are translucent white with two dark lines enclosing 

 a broad, elongated area on the back which is pale and outside of 

 which the sides of the mantle are finely gray-dotted. The foot and 

 whole underside are pale waxen but the oculiferous tentacles are 

 conspicuous by their dark slate color in contrast to the rest of the 

 animal. 



The adult is of a purplish livid color in general, though some- 

 times albinistic ; the back shows a narrow light median dorsal line, 

 and two broad somewhat hazy dark bands corresponding to the 

 dark lines of the young, but the pale dorsal area is more or less 

 clouded with grayish purple. The genital pore is not so close to the 

 foot as in Dr. Pilsbry's specimens from Bermuda, and the lighter 

 dorsal area is broader in Bahama specimens. The animal itself, 

 as far as one can determine from alcoholic specimens, is rather 

 broader and stouter than the Bermuda variety. It measures, in two 

 specimens ; total length 54 and 63 mm., breadth 25.5 and 26.5 ; the 

 sole is 9 and 10 broad, and 54.5 and 62.5 long ; the genital pore is 

 distant from the anterior edge of the mantle 31 and 33 ; from the 

 posterior edge of the mantle 23 and 27 ; from the sole 3 and 2.5, from 

 the lateral edge of the mantle 5 and 6 mm. 



Numerous specimens were obtained at Nassau, and it is probably 

 widespread, but rarely noticed by travelers because it is nocturnal 

 in its habits. It seems to have been the only slug noted during the 

 expedition. 

 Segmentina (Planorbula) dentata Gould. 



Mangrove Cay, Andros. 



Mr. Bryant writes "I found all the Planorbis in dried up pond 

 holes in the lime rock near what is called the " shore road," really 

 a path, about a mile from the village of Mangrove Cay. When I 

 saw them there had been little rain and there was nothing but mud 

 with some grass and reeds growing in it, and one or two crab holes 

 where there was still some water and very soft mud. Near the top 

 of the holes and over most of the bottom were scattered large 

 numbers of dead Planorbis and a few Phvsa. The first hole I ex-
