crenulato : facies interna, albida, spadiceo sordidata ; limbo lato, 

 fusco et albo tessellato. Long, -fij, lat. -^q, alt. -^q poll. Hab. 

 Bay of Valparaiso. 



A small, rather smooth shell, arched in every direction, in 

 consequence of attaching itself to other shells. When fresh it is 

 very prettily radiated. 



Patella (Lottia ?) textilis. Testa depressa, oblique conica ; 

 apice anteriori, acuto ; costis latis, elevatis, subplanulatis, nodosis 

 ad 15 radiantibus ; epidermide viridi, punctis albidis quadratis 

 reticulato : basi ovato-rotundato, limbo marginali albido et fusco- 

 viridi fimbriate : facies interior albida ; fundo piceo. Long. 1, 

 lat. I-, alt. -f^ poll. Hah. Straits of De Fuca and Killimook. 



Like some varieties of P. viridula ; but its base is less orbicu- 

 lar, its color is darker green, and the reticulations are finer and 

 less in zigzag ; the ribs are less numerous, nodular, and not paler. 

 Its remote locality favors the idea of its being distinct. 



Patella (Lottia ?) scabra. Testa parva, scabra, per-inequila- 

 teralis, oblique arcuato-conica, pallide virens, nigro diversemode 

 virgata, costis radiantibus scabrosis ad 15 ornata ; basi ovata : 

 facies interna albida ; fundo piceo, limbo marginali viridulo et 

 piceo fimbriate. Long. |, lat. f, ah. | poll. Hob. San Fran- 

 cisco. 



About the same size, and may be only a variety, of P. textilis. 

 Its arched form, rough surface, coarse black stripes, and difierent 

 locality, seem to warrant its separation. 



Patella (Lottia.?) araneosa. Testa parva, tenuis, depresso- 

 conica, sub-equilateralis, Isevis, pallide virescens, ramulis rubigi- 

 nosis araneosis reticulata : facies interna albida ; margine sim- 

 plici, acuto ; limbo marginali planulato, rubiginoso, radicoso. 

 Long, f , lat. ^, alt. ^ poll. Hah, Sooloo Sea. 



A pretty little shell, most probably a Lottia, resembling some 

 of the species figured by Quoy, especially his orbicularis. In- 

 deed it is so like the reticulated variety figured in PI. LXXI. fig. 

 33, that the examination of a more extensive series might show 

 them to be identical.
