Pulmonifera of Maine. 37 



A portion of the lingual membrane had about twenty rows of plates, with 

 12-1-12, central plate long and narrow, with three minute denticles ; laterals 

 nearly square, their outer posterior edges indented, having one long inner den- 

 ticle the length of plate, and smaller outer denticle. Uncini as in all these 

 species, gradually ditTering from laterals, marked with four or five minute 

 denticles, inner one prominent. (PI. 10, Fig. 88.) 



Pupilla badia, Adams. {Fig. 89.) page 38. 



Found under stones and in the grass in open fields, and along 

 the road sides near the sea, in the vicinity of Portland. It has 

 never been found inland in this State. 



Near Fort Preble in Portland Harbor, over twelve hundred 

 specimens of this species were collected in an hour, the situation 

 was within a rod of high water mark. 



Occurs at Anticosti, and the Mingan Islands Gulf of St. 

 Lawrence. ( Verrill.) 



Coarse interrupted wrinkles mark the peri ostraca; apex granu- 

 lated ; in most adult specimens the periostraca is entirely effaced 

 from the apex. This species is ovoviviparous, having been found 

 with fully developed young in November. Three or four embryos 

 only were detected in each specimen. 



The allied European species is also ovoviviparous. {Moquin 

 Tandon.) 



Buccal plate, [Fig. 91,) slightly curved, cutting 

 edge waved. 



Lingual membrane, 90-14-1-14, central plate 

 longer than broad, tridentate ; laterals bidentate. Fig. 91. 



also shghtly shouldered on the inner side at the base of larger denticle ; uncini 

 denticulated, inner denticle largest. (PL 10, Fig. 92.) 



Though I have examined hundreds of specimens of this species 

 collected in the vicinity of Portland, Maine, I have never been 

 able to find a trace of the parietal tooth which Adams mentions 

 in his description of P. badia, and which is represented in the 

 drawings of this species ; specimens of this species collected by 

 Mr. A. E. Verrill, from Anticosti and the Mingan Islands, were 

 also devoid of this tooth. 



Pfeiffer, Forbes and Hanley consider this species identical with 

 the Pupilla muscorum of Europe. The differences will be seen at
