102 PHYLLONOTUS. 



size of the finest Indian Ocean specimens. Dr. Fischer has de- 

 scribed M. hoplites, (fig. 226), from the West African coast 

 distinguishing it by possessing eight varices instead of six, and 

 by its smaller size. The specimens before me are seven to eight 

 variced, and some of them correspond well with the figure of M. 

 hoplites. A starved condition of the animal is shown by the 

 multiplication of varices or rest periods, less luxurient spines or 

 fronds and smaller size : such is M. hoplites. I cannot doubt 

 its identity with M. saxatilis. 



M. ENDIVIA, Lam. PI. 26, figs. 227-229. 



Whorls ventricose, becoming flat-shouldered and thick with 

 age ; transversely ridged and striated ; with six to seven frond ose 

 varices, the fronds elevated, recurved. Yellowish-brown, fre- 

 quently banded with a darker tint, fronds usually dark brown or 

 blackish ; aperture white, or lips tinged with pink. 



Length, 4 inches.

Mr. Broderip described the variety with declinate, flat shoul- 

 ders as M. saxicola, and Dunker has called it M. depresso- 

 spinosus (fig. 229) ; it bears the same relation to the typical form 

 as does a variety of the Mediterranean species M. trunculus. I 

 have seen specimens of an all-white variety (var. albicans) from 

 the Philippines. 



M. Norrisii, Reeve (fig. 228), (no locality given), appears to 

 me to be the young of var. albicans. 



M. COEONATUS, A. Adams. 



An ovate-trigonal shell, fuscous, with conical spire ; there are 

 six flattened whorls, angulated behind, with four revolving lirae 

 and numerous intermediate smaller ones ; seven varices, fim- 

 briated and laciniated, widely uncinate behind; aperture oblong, 

 acuminated in front, outer lip fimbriated ; canal short. 



Tsusaki, Japan ; 35 fathoms. 



" A somewhat small, neat species, with the whorls very prettily 

 coronate." No dimensions are given. Appears to be related to 

 the preceding species. Sowerby (Thes. Conch., fig. 199), has
