CRUSTACKA WUITKLKaGE. 101 



There is a pair of gastric spines which are about 03 mm. aparL> 

 their tips scarcely reaching to the base of the rostrum ; se\eral 

 small spinules occur on the surface of the carapace near the 

 antero-lat(n'al border ; the latter is armed by eleven spines, three 

 on the front over the space between the eye-stalk and the outer 

 antenna, and one on the side below the insertion of the latter ; 

 the remainder forma lateral linear series, the posterior one ])eing 

 situated on the angle of the peimltimate ridge. 



The rostrum is Hat, straight, about 2-2 mm. long and 1"3 mm. 

 wide at the base ; the sides have six equal spines, three on each 

 margin; the terminal spine is I'l mm. long and exceeds the distal 

 pair by 0-7 mm.; there is a smaller pair of spines near the base 

 of the rostrum, one on each inner angle of the front. 



The third maxillipedes have the ischium and merus joints equal 

 in length — measured from the base to the actual apex in each 

 case. The inner distal extremity of the former terminates in a 

 small spinule ; the outer is somewhat obliquely produced but not 

 acute ; the longitudinal (cutting) ridge on the anterior surface 

 bears about twenty-four denticles ; there are also six or seven in 

 the same line on the preceding joint. The merus has two strong 

 spines on the inner border, one in the middle and the other 

 situated between it and the distal margin. The outer border is 

 rounded and smooth.

The specimens recorded under this name in the " Challenger " 

 Report by Henderson are probably distinct. In the description 

 the gastric spines are said to be absent, which is not the case in 

 G. aculeata, Haswell.

There are three examples of what appears to be a new species, 

 but unfortunately they are imperfect; the larger limbs are wanting. 



The carapace is 3-5 mm. long by 3 mm. wide; the striae are 

 fine and about ten in number; rostrum 1-2 mm. long and 0-7 mm. 

 wide at the base, straight, rather deeply grooved, with three pairs 

 of lateral spines ; the lowest pair have their tips separated by a 

 space equal to the base of the rostrum ; the following pairs are 

 much closer together, owing to the inflection of the margins, the
