162 BULLETIN OF THE 



verse bands of red, three of which cross the merus. The abdomen and sternum 

 are granulated. 



Length, 13 mm. ; breadth, 18 mm. ; length of ambulatory leg of second 

 pair, 34 mm.; merus of do., 9.3 mm. ; carpus, 5.6 mm. ; propodus, 9 mm.; 

 dactylus, 7.5 mm. 



Station 3355. 182 fathoms. 4 males, 1 female. 



Cymopolia zonata Eathbun (Proc. U. S. Nat. Mus., XVI. 259, 1893), lately 

 described fiom the Gulf of California, 40 fathoms, differs from ft tuberculata as 

 follows. The carapace is narrower and more quadrangular. The median lobes 

 of the front are small and inconspicuous, while the lateral lobes are very broad 

 and are separated from the median lobes by a slight, shallow notch. In ft tu- 

 berculata the four frontal lobes take on the form of prominent triangular teeth, 

 clearly separated from each other by deep triangular sinuses. The antero- 

 lateral margin of the carapace is three-toothed in ft zonata, four-toothed in 

 ft tuberculata. The tubercles near the posterior margin of the carapace are 

 more elongated in the former species than in the latter. The hand of the 

 former is much broader, and is armed with prominent spiny tubercles. 

 Finally the meri of the ambulatory legs are much shorter in ft zonata, and are 

 armed at the distal end with a blunt triangular tooth, while in ft tuberculata 

 this tooth is transformed into a long sharp spine, and a pair of smaller spines 

 is present, one on each side of the proximal end of the carpus. 



Family RANINID^!. 



Raninops fornicata, sp. nov. 



Carapace very convex from side to side, naked, smooth or nearly so, punc- 

 tate. Rostrum acute, lightly carinate, the carina extending backward for a 

 short distance on the carapace. Superior margin of orbit armed with three 

 acute teeth, the second of which is curved forward ; the anterior tooth is sep- 

 arated from the rostrum by a deep rounded sinus, from the second tooth by an 

 angular notch ; the second tooth is separated from the third by a nearly 

 straight interval ; the third tooth lies some distance in front of the posterior 

 end of the orbit. Back of the orbit there is a strong procurved spine on the 

 margin of the carapace. Eyestalks compressed, equal in length to one half 

 the width of the carapace. Second segment of the third maxilliped equal to 

 the third joint, crossed by a piliferous line; third segment notched at the an- 

 tero-internal angle. Cheliped : merus unarmed, microscopically spinose above, 

 setose below ; carpus minutely rngoso-spinulose, the superior distal angle pro- 

 jecting as a sharp tooth ; propodus lightly rugose, upper and lower borders 

 margined, unarmed, palmar edge irregularly and inconspicuously toothed ; 

 dactylus without any prominent tooth. The dactylus of the fourth pair of 

 legs has a very convex internal border, the dactylus of the fifth is long, narrow, 

 and spatulate. Abdomen setose ; telson obtuse at the end. 



Length of carapace, 12 mm.; breadth, 8.6 mm. 



Station 3369. 52 fathoms. 1 specimen.
