Allied to P. tramoserica, but its colors are generally dull and 

 dead, instead of silky. Generally, eight or ten of the ribs are 

 more prominent than the rest The prevailing color of the in- 

 terior is that of ripe muskmelon. Sometimes there are dusky 

 spots between the ribs. It seems to be found at all the islands of 

 the Paumotu group, and as far as Taheiti. 



Patella luctuosa. Testa oblique conica, crassa, vertice 

 eccentrica, obscure olivacea, interdum sanguineo tincta, costis ma- 

 joribus ad 12 rotundatis, scabrosis, pallidis, minoribus quibusdam 

 interjectis : apertura ovalis ; margine crenulato : facies interna 

 livida, reflexionibus succineis micans ; limbo fasciis fuscis et al- 

 bidis inequalibus alternantibus radiate. Long. 1;^, lat. 1, alt. -J 

 poll. Hab, New Zealand. 



Unusually rough and irregular of surface, not unlike coarse 

 specimens of P. vulgata, but the interior sometimes rivals P. ira- 

 moserica. 



Patella pipekata. Testa sctbrida, oblique conico-depressa, 

 olivacea, costato-striata, costis majoribus pallidioribus cum lineis

 tura ovata ; margine crenulato ; facies interna livida, fundo ferru- 

 gmeo, radiis albidis insigni. Long. 1|^, lat. y^^, alt. ^ poll. Hob.

Somewhat like what I suppose to be P. scutellaris, from the 

 Mediterranean, especially its interior, but more elevated and less 

 elongated. 



Patella instabilis. Testa olivaceo-cervina, elongata, ele- 

 vata, ad latera compressa, creberrime radiatim striata, apice sub- 

 centrali, obtusa, castanea : apertura oblongo-elliptica ; margine 

 integro : facies interna lactea. Long. 1^, lat. ^^, alt. y^^r polh
