line with the hepatic spine, and a much larger tooth, placed about 

 one-third the length of the carapace from its hinder margin. There 

 is also a strong hepatic tooth. The carinal tooth of the first abdominal 

 segment is strong, triangular, with the apex directed forward. The 

 fifth and sixth segments have each a median tooth on the posterior 

 margin on either side of which there is a slight excavation, followed 

 by a small tooth. The abdominal segments are sculptured by carinae ; 

 the epimeral margins are rather broadly rounded except that of the 

 fifth segment which has a sharp denticle at its posterolateral angle.

Plate 39. 



Material examined: Two specimens taken S. by E. of Monaco 

 Harbor, Mediterranean Sea; depth, 900 fathoms, April 19, 1927, by 

 the ''Ara," "William K. Vanderbilt, commanding. 



Color: The exquisite color-plate of this schizopod in the Monaco 

 Report shows two color phases, one in which the carapace and anterior 

 dorsal region of the abdomen are red with freckle-like spots of deeper 

 red; the anterior and entire posterior parts of the abdomen creamy; 

 in the second figure the coloration is the same, except that the red of 

 the carapace is deeper and there are black splotches in the hinder 

 two-thirds of the dorsal region of the carapace. 



Discussion : This species, with its various growth stages, has been 

 so frequently taken and described that it is one of the best known 

 members of the genus.
