CHRYSAME. 145 



Sowerby considers this species as well as M. nucleola, Lam., 

 identical with M. fraga, Qnoy. The latter is apparently the 

 young of M. cucumerina ; the former is more like this shell in 

 form but has not its markings, and the sculpture appears to be 

 different. 



M. porcata, Humph, (fig. 237), appears to be a synonym, and 

 M. miniata, Anton (fig. 238), as figured by Kiister can scarcely 

 be different. M. spadicea, Dunker (fig. 224), is placed in the 

 S}monymy by Garrett ; it is darker and smaller than the 

 type, but usually spotted with white on the tubercles, although 

 not so represented in the figure, copied from Sowerby. It may 

 be considered a variety.

M. GRACILIOR, Carpenter. PI. 42, fig. 239. 



Red-brown, with sharp revolving lines, decussated at the upper 

 part of the whorls -by longitudinal riblets ; plications of the 

 columella inconspicuous. H., -2 inch.

Dr. P. P. Carpenter named but did not describe this minute 

 species ; he. referred it to Mitromorpha, a group belonging to the 

 family Pleurotomidse. Mr. Henry Hemphill, of San Diego, Cal., 

 collected the original lot and it is from one of these that the 

 figure is drawn. It is one of several similarly sculptured minute 

 species occurring on the California coast. I figure it here to call 

 attention to the group, as they may be Mitrids, although most 

 probably Pleurotomae. 



M. NUCLEOLA, Lam. PL 3^, figs. 145-147. 



Dark red ; the revolving ribs decussated by longitudinal sculp- 

 ture. Length, 1 inch. 



Indian Ocean ? Java ? 



As already mentioned, Sowerby makes this species equivalent 

 to M. fraga, Quoy, and M. peregra, Reeve : from the former it 

 differs in form, from the latter in color and sculpture. Reeve's 

 figure of it is so different from that in Kiener, that I doubt if it 

 belongs to the same species. That Kiener's figure is not a good 

 one^is self-evident ; still it is the only authentic illustration, and 

 I have therefore copied it.
