Achatinella and other Pulmonata. 349 



Though we retain the species iu the geuus Pupa it must be remembered 

 that as treated by Pfeiffer it would be placed in BuUmimis of Albers and 

 Martens. In general form of shell it certainly approaches Buliminus 

 montaniis, Drap. 



lilmax ne^vstOEil, J. G. Coop. 



San Francisco, received from Mr. Stearns. We presume 

 the specimens belong to this species. 



Jaw and lingual membrane as usual in the genus. No bifurcation to the 

 marginal teeth. Teeth about 30-1-30, with fourteen perfect laterals. 



The teeth are quite of the shape of those figured on p. 59 of our L. and 

 r. W. Shells. The side cusps of the centrals and laterals are well devel- 

 oped. 



Xlrinna. ^e«vcom1>i, A. Ads. 



In the collection of the late Mr. Robert Swift, presented 

 by his daughter, Mrs. A. L. Washburne, to the Academy of 

 Natural Sciences of Philadelphia, but temporarily in the 

 charge of Bland, he found specimens of this species, given 

 to Mr. Swift by Dr. Wesley Newcomb. 



The genus SJrinna, referred to the family Limncetdce, was 

 described by H. and A. Adams, iu the Zool. Proc, 1855. 



The authors remark, "This shell (J^. JSfeivcomhi) by some 

 would be referred to JSTeritina, by others to Limncea, and 

 possibly by a few to the genus Otina; it appears, however, 

 to be distinct in character from all these." 



From one of the specimens in the Swift collection the jaw 

 and lingual membrane here described were obtained. 



To satisfy himself as to the shells, Bland sent one for ex- 

 amination to Dr. Newcomb, who in reply has kindly furnished 

 the following information as to the habitat and station of the 

 species : — 



, "The specimens were forwarded by me to Mr. Swift iu 

 about 1852 or 1853. They were collected high up the stream 

 called the Hanelei River, on the Island of Kauai. At a fall 

 in this river, the spray is thrown over the rocks, keeping 

 them constantly wet ; from these rocks the shells were taken.
