Species 13. (Mus. Cuming.) 



Chepidcla arenata. Crep. testa subobliqueovatd.lavi, 

 epidermide tenumimd versus marginem indutd, albidd, 

 /usco-rufo creberrime punctata, intun cartieo-albd ; ap- 

 pendice breviuHCuld, opali-albd. 



The sandy Crepidula. Shell rather obliquely ovate, 

 smooth, covered towards the margin with a very thiu 

 epidermis, whitish, very closely dotted with brown- 

 red, interior flesh-white; appendage rather short, opal- 

 white.

llab. St. Elena, West Columbia (from sandy mud, on shells, 

 at a depth ranging from six to eight fathoms) ; Cum- 

 ing. 

 Characterized by a sprinkled painting of red dots, and 



closely allied in this respect to C.fornicata. The locality, 



' I.-^land of St. Helena,' given by M. Deshayes, is a slip of 



the pen in copying the Cumingian habitat. 



Species 14. (Fig. a, b, Mus. Cuming.) 

 Crepidula foliacea. Crep. testd suborbicalari, rude 



verrncoso-foUaced, albd,ferrugineo-fiisco radiatim stri- 



gatd; appeiidice iuternd paniuscwld, siibcoiicam, medio 



dilataid. 

 The foliaceous Crepidula. Shell nearly orbicular, 



rudely wart-leaved, white, radiately streaked with 



rust-brown ; internal appendage rather small, slightly 



concave, dilated in the middle.

 Cahjptrcea strigata, Broderip. 

 Hub. Shores of Peru (adhering to shells and stones) ; 



Cuming. 

 This species has two well-marked characters, a coating 

 of rudely developed leafy warts, and a faint colouring of 

 rust-brown rays diverging from the umboes, and some- 

 times leaving a white ray-like hiatus. This last-named 

 state Mr. Broderip named with some doubt C. strigala, 

 thinking it might prove to be a variety of C. dilatata. 



fusco divaricatim strigatd, intus carneo-aWd ; appendice 

 opali-albd, subdepressd. 



The arched Crepidula. Shell somewhat oblong-oval, 

 boat-shaped, incurved at the apex ; smooth, whitish, 

 divaricately streaked throughout with flesh-brown, 

 interior flesh-white ; appendage opal-white, rather de- 

 pressed.

Hab. United States. 



In this fine species the painting is sometimes in dots, 



especially towards the margin. 



Species 15. (Mus. Cuming.) 

 Crepidula founicata. Crep. testd suboblongo-ovatd, 

 naviformi, apice iiicurvd, complanatd, albidd, carneo- 



16. (Fig. a, b, Mus. Cuming.) 



Crepidula Lessonii. Crep. testd oblique ovatd, sub- 

 planatd, undique concentrice laminato-fimbriatd, dia- 

 phano-albd, fusco-rttfo radiatim lineatd, intus ad Tnar- 

 ginem fusco-rufo ciliato-strigatd ; appendice medio 

 elevatiuscuM, ad latus subemarginatd. 



Lesson's Crepidula. Shell obliquely ovate, rather flat, 

 concentrically laminarly frilled, diaphanous-white, 

 radiately lineated with brown-red, hair-streaked 

 round the margin with brown-red ; appendage 

 rather raised in the middle, slightly notched at the 

 side.

Hub. Island of Muerte, Bay of Guayaquil (under stones, at 

 low-water) ; Cuming. 

 This elegant species is constructed in layers, which form 



a series of concentric laminary frills. It is of a subtrans- 



parent white texture, more or less densely rayed with 



brown-red lines. 



Species 17. (Fig. a, b, Mus. Cuming.) 



Crepidula Walshi. Crep. testd transverse ovatd, planu- 

 luld, //pice oblique lateraliter ittcurvd, diaphano-alhd ; 

 appendice plano-dilataid, ad latus obsoleti inflexd. 



Walsh's Crepidula. Shell transversely ovate, rather 

 flattened, obliquely laterally incurved at the apex, 

 dia|)hanous-white ; appendage flatly dilated, obso- 

 letely inflected at the side.
