Chiton incanus. 



T. sollda, oblong o ovalis, valde convexa, cinereo et nigro variegate 

 concenfrice undulato striata, granulis sparsis nigris aspersa, a% 

 dorsum subcarinata et longitudinaliter nigro bifasciata ; areis 

 lateralibus vix distinctis, margins aculeis inequalibus curtis, curvatis 

 nigris et canescentibus induta. bong, y 1 ^, lat. ~ poll. Hab.

Like 0. piceus, Gray, and still more like G. petholatus, which 

 has a hairy margin.

T. ovalis, parva, convexa, tenuis, cinnamonea, cum striis 

 radian tibus, tenuibus, confer tissimis imbiicato asperis ; apice acuto, 

 antico, ad marginem valdo declinato ; apertura margins antsrior

Closely allied to P. galathea, Lamarck, which, however, is snow 

 white, more circular, the apex more central, and the striae much 

 coarser. 



[This diagnosis is obscurely brief, but appears to refer to a 

 Svphonaria. — J. E. T. W.] 



Haliotis crispata. 



T. parva, tenuis, convexa, elongato ovalis, undidis obliquiis, 

 angulatis, divaricantibus rugata, spiraliter striata, rubida ; sjpira 

 elevata, submediano, foraminibus parvis, circularibus, confertis, 

 ad septennis perviis, exirorsum canaliculatis, intus undulosa, nitida

With N\ Holland shells. About the size and form of H. 

 stomatioB-formis, Reeve, but distinguished from all others by its 

 crowded angular ripples arranged somewhat like- the colors of 

 H. ziczac. No shell approaches it in this respect, except the 

 very young of H. australis. 



[Very probably a young variety of H. ncavosa, of which H. 

 australis is a synonym. In the shape and the undulations 

 referred to that species is extremely variable. J. E. T. W.]
