 Sjpondylus sinensis. Spond. testd Icevi, elongato-ovali, ared car- 

 dinali plerumque elongatd ; costis 5 ad 6 principalibus, vix elevatis, 

 squamis Icevibus, depressis, palmatis ; interstitiis Icevibus, costis 

 incequalibus et squamis minoribus ; colore pallidefulco, vel roseo, 

 vel albo, prope umbonem fusco variegato. 

 Remarkable for the smooth, depressed, palmated, spoon- shaped 

 scales on the five or seven principal ribs, which are repeated in mi- 

 niature in the interstices. 

 From China. 



Spondylus lingua-felis. Spond. testd ovali, crassd, ared cardi- 



nali et auriculis magnis ; costis numerosis, vix elevatis, spinis 



brevibus, cequalibus, numerosis armatis ; colore fusco, subtus croceo. 



A much more solid shell than S. asperrimus, with the hinge large ; 



the colour is a uniform dark brown, which is shown in the interior 



by a well-defined border. The shell is covered by nearly equal ribs, 



which are armed by short, thick, slightly curved prickles.

Spondylus digitatus. Spond. testd subrotundatd, tenui, costatd; 



costis 6 ad 9 principalibus, vix elevatis, squamis rectiusculis, 



arcuatis, ad terminos palmatis, aculeatim divisis ; interstitiis spi- 



nosis ; colore fusco, vel rubra, vel purpureo, ad umbones rubro 



variegato. 



The peculiarity of this species consists in the beautifully branched 



and digitated palmations which terminate the erect and arched 



scales.

Spondylus tenuispinosus. Spond. testd ovali, tenui, costis prin- 

 cipalibus 8 spinis elongatis, tenuibus, erectis, numerosis, spinis in- 

 terstitialibus minutis ; interstitiis minute imbricatis ; laminis valvce 

 superioris elegantissime foliaceis ; colore pallide cinereo , prope um- 

 bonem rubro variegato, valvce inferioris albo, prope umbonem fla- 

 vido rubro radiato. 

 This species is distinguished by the thin, sharp, erect, white spines 

 which ornament the numerous ribs. The upper valve is of a pale 

 ashy colour, variegated with red near the umbo, and the under 

 valve is white, with beautifully foliated laminse and a few graceful 

 spines.
