THE NAUTILUS. 107 



ON WEST MEXICAN LAND AND FRESH-WATER MOLLUSCA. 



( 'ATALOGUE OF MARINE SHELLS * * * LOWER CALIFOR- 

 NIA. By J. G. Cooper (Proc. Cal. Acad. Sci., IV, V). 



In the first of these papers, Margaritana subangulata is described 

 and figured as new, and the following species are figured: Anodonta 

 decurtata Conr., Ano. nuttaUiana var. tiynitim Coop., Limncea con- 

 tracostce Coop., Plnnorbis pabloanua Coop, and Amnicola yatesiana 

 Coop. 



In the second, land shells collected about 25 miles north of Cape 

 St. Lucas are considered. Bulimulus decipiens being described as 

 new. The generic name Plicoliimna is proposed for Rhodea var. 

 ramentosa Coop. ; it is therefore equivalent to Dull's Pseudorhordea 

 (Nautilus, Sept., 1895). The Melaniella ei&eniana J. G. Coop, is 

 referred to Strebel's genus Pseudoiubulina, a group of Glcmdinidce, 

 on evidence of the dentition, which has been worked out by Dall. 



In his paper on West Mexican Land Shells, Cooper announces 

 the presence of the northern forms Conulus fulvus, Hyaliuiu inde,n- 

 tata, Limncea columella, Sphcfrium partumeiitnivar. tmneatum,from 

 Tepee, south of Mazatlan, as well as other species belonging to the 

 Mexican fauna. 



The last paper enumerates marine shells collected mainly by Mr. 

 W. E. Bryant, including; some interesting forms, but no new species. 



NOTES AND NEWS. 



PLOVER CAUGHT BY A PINNA The article in the September 

 number, "A Sora Caught by a Mussel," recalls a similar incident 

 which I observed at New Pass, Sarasota Key, Fla. It was after a 

 heavy storm, and there was a large number of Pinna muricata 

 washed ashore. On my return to the boat after collecting some 

 shells, I observed a Killdeer Plover that seemed very tame, but on 

 a closer examination I found that it was caught by a Pinna. In 

 this case it was caught by the bill. Its tongue was bleeding and 

 the bill was indented by the sharp edges of the shell. It was with 

 some difficulty that I removed the shell and let the Plover go re- 

 joicing on its way. E. J. Post.
