78 STALK-EYED CRUSTACEA. 



appears to represent on the Pucific side of America. When compared with 

 the type specimens of JI. stimjjsom tlie differences are very evident, though 

 somewhat difficult to describe. The carapace of 31. gracillpes is much flatter, 

 smoother, and more shining than in M. dimpsoid ; the transverse ridges are 

 more prominent, fewer in number, and do not show that tendency to break 

 up into imbricated, granulated scales which is so characteristic of J/, stiiiipsoni. 

 The supraocular spines are shorter, closer to the median rostral spine, and 

 fused more completely with the latter at the base. The eye is larger, the 

 transverse ridges on the abdominal soniites fewer in ninnber. The lateral 

 spines of the carapace and the abdominal spines are more fully developed. 

 The cardiac area is narrower and bounded by more distinct furrows.

Compared with the type specimens of M. microiMlmlnia, the " Albatross " 

 specimen has the rostrum shorter and less strongly upturned; the supra- 

 ocular spines, too, are shorter (shorter than the eyes). There is no row of 

 spines, but merely a ridge, along the superior or external face of the hand. 

 The second abdominal somite bears only two spines instead of eight, as in 

 the type ; but this is of no great importance, since the spines of that segment 

 are altogether absent in one of the " Blake " specimens (Station No. 2), and 

 in one noticed by Henderson in the " Challenger" collections. 



M. micropMhalma was taken by the " Blake " among the West Indies in 

 573-1030 fathoms, and by the " Challenger " in the same region in 390 

 fathoms, north of Kermadec Islands in 600 fathoms, and near Ascension 

 Island in 425 fathoms.
