suturis parvis ; mucrone vix monstrante ; intus virescente, rufo 

 tincta ; marginibus valvarum valde sinuatis, sinu angulato ; ad 

 jugum vix impressa ; limbo valde piloso, setis longis, fortibus, 

 incurvatis. 



Long. 1-05, lat. -8, alt. -22, poll. 



Hab. San Diego ; olim legit T. Nuttall. Mus. suo. 



The sculpture of this species is very strongly marked ; the mar- 

 ginal hairs rather long, short and crowded*. 



16. Patella ?toreuma, var. tentjilirata. 



P. t. valde depressa, oblonga, diaphana ; colore corneo, fusco-pur- 

 pureo irregular iter fammato; liris circiter xxii., tenuissimis , inter- 

 stitiis obsolete striatis ; apice subprominente , circiter quinla parte 

 longitudinis sita ; pagina interna valde iridescente. 

 Long. 1-38, lat. 1, alt. '28, poll. 

 Hab. Monterey ; legit — Hartweg. Mus. Cuming. 

 This shell appears to agree with P. toreuma, Rve., in all essential 

 respects ; but instead of the fine regular striae of that species, there 

 are a few delicate principal ribs, with obsolete striae between. As its 

 neighbour, P. Oregona, sometimes developes large ribs, and is at 

 other times nearly smooth, this has not been considered a sufficient 

 difference to constitute a species, until more is known of its variable 

 powers. 



17. Galerus? sinensis, var. fusctjs. 



G. ? Sinensis, t. rufo-fusca, hue et illuc lineis declivis instructa. 



This shell, marked " Gulf of California," Mus. Cuming, but with- 

 out authority, differs essentially from G. mamillaris, Brod. irregu- 

 laris, C. B. Ad.), and is not to be distinguished from the British 

 specimens of G. Sinensis, except by the colour, and by a few irre- 

 gular diagonal lines here and there, which are probably an individual 

 peculiarity. In the collection of R. M 'Andrew, Esq. are several 

 specimens of the true G. Sinensis from the Mediterranean, of an 

 equally dark colour. It is impossible, therefore, to found a specific 

 distinction on this circumstance alone. It is here described in order 

 to direct the attention of collectors in that region to the subject. It 

 would be very remarkable should the species be proved to inhabit 

 so remote a locality. The specimen in question may have been 

 imported. 



18. Galerus subreflexus. 



G. t. irregulari, conica, rufo-fusca, radiatim tenui-striata ; striis 

 aculeatis ; sutura impressa ; vertice involuto, apice depresso ; 

 lamina interna apicem versus ad duas trientes reflexa, umbilicum 

 magnum monstrante, margine dilatata, baud angulata. 



Lat. *75, alt. -4, poll. 



Hab. In Sinu Californiensi. Mus. Cuming. 



* The specimens described not being my own property, I did not dare to ex- 

 amine the insertions of the valves with a view to determine the genus. It is pos- 

 sible that some of these species have been already described by Dr. Gould in the 

 Expedition Shells (pp. 5, 6), the plates to which are, alas ! not yet published.
