THE PACIFIC COAST. 17 



pressed granules ; tentacles black, acutely pointed ; eyes 

 at the base of superior tentacles ; anatomy believed to re- 

 semble, somewhat, that of the Lymniadae. Gregarious ; 

 in its habits resembling Lymnaea, being found always near 

 water, and laying its eggs on the water-cresses and other 

 aquatic plants. Arrives at maturity in one year, one half 

 the time required by the other species."

 Helix Baskervillei Pfeiffer, 1. c. iii. 2.30. 



There can be no doubt of the identity of these two 

 species. Gould's original specimen agrees perfectly with 

 the figure of Reeve (1. c.) and Pfeiffer's description. The 

 latter remarks on H. Baskervillei " Conf. H. devia Gould, 

 huic forsan peraffinis." 



The shell figured is preserved in the Cumingian collec- 

 tion. 



HELIX KELLETTI Forbes. 

 Plate LXXVI. Figure 12. 



H. testa anguste umbillcata, depresso globosa, tenui, rugulosa, granu- 

 lata, fulva, spira subturbinata, sordide flavo conspersa, rufo-unifasciatS, 

 anfr. 6 convexiusculi, ultimo ad peripheriam fascia pallida cincto, basi 

 subinflato; apertur^ lunato-rotundata, intus pallide fusca, unifasciata ; 

 perist. reflexiusculo, margine columellari dilatato, reflexo, umbilicum 

 occultante. Diaiii. max. 22, min. 19, alt. 19 mill. 



This species is neai'ly allied to H. Galiforniensis Lea. It differs 

 in the more pyramidal contour of the spire, in the less tumid body 

 whorl, and consequently differently shaped, more lunate, slightly 

 elongated mouth. The margin of the mouth is more reflected.
