 Acmcea elegans, Philippi. 



Hab. La Guayra. 



The specimens represented at Fig. 115 and 118 of this 

 Plate prove, on minute examination, to be different forms 

 of the same species. The dark pencilled rays are peculiarly 

 broken up and white-mottled about the apex, and conspi- 

 cuously neatly tessellated on the inner margin. 



Species 116. (Mus. Cuming.) 

 Patella cijieliata. Pol. testa ovatd, subconicd, apice 

 cetitrali, elevato, radiatim costatd, costis angnstis, sub- 

 disfantibiis, iuterstitiis obscure clathratis ; lutescente- 

 albd, costis opaco-albis, interstitiis prmniscue sangid- 

 neo-tinctis, iutiis opaco-albd. 

 The jewelled Limpet. Shell ovate, subcouical, apex 

 central, raised, radiately ribbed, ribs narrow, rather 

 distant, interstices obscurely latticed ; yellowish- 

 white, ribs opake-white, interstices promiscuously 

 blood-stained, interior opake-wlute. 

 Ilab. Honduras; Dyson. 



A very characteristic blood-red stained shell, the surface 

 being obscurely latticed between radiating opake-white ribs. 



Species 117. (Mus. Cuming.) 



Patella stipulata. Pat. tesld suboblongo-ovatd, antice 

 suhacmiiinatd, depresso-coHve.vd, apice centrali, snb- 

 acuto, radiatim liratd, liris rudibns, coii/erlis, valdi 

 irregularibus, subimdulatis, margine subacute produc- 

 tis ; virescente-nigrd, litieis perpaucis albidis obscure 

 radiatd, intiis intense cteruleo-viridi, margine nigri- 

 cante. 



Tue thatched Limpet. Shell suboblong-ovate, a little 

 acuminated in front, depressly convex, apex central, 

 rather sharp, radiately ridged, ridges rude, close-set, 

 very iiTCgular, a little waved, rather sharply produced 

 at the margin ; greenish-black, faintly rayed with a 

 few whitish lines, interior deep blue-green, margin 

 blackish. 



Hah. Panama. 



A dark closely irregularly wave-ridged shell, the ridges 

 here and there produced over the margin. The interior is 

 of a peculiar deep blue-green. 



Species 119. (Mus. Cuming.)

 depresso-conoided, imdiqiie creberrinie scabroso-costatd

NuTTALL, Jay's Catalogue of Shells. 



Ilab. Upper California. 



A very characteristic species, both in sculpture and 

 colouring, sometimes of much larger size than the speci- 

 men here figured, with the character, however, in that 

 case more or less obscured by abrasion.
