at the tip, which is rounded and bears five spines; there are two 

 pairs of lateral spines. 



The antennules measured to the tip of the longer flagellum are 

 only a httle shorter than the carapace, the peduncle forming about 

 half their length. The first segment of the peduncle is about equal 

 to the other two together and the three are beset with rather numer- 

 ous setae, apparently of considerable length, although nearly all of 

 them are broken off in the specimens examined. The longer flagellum 

 has six long segments and a minute terminal one in two of the 

 specimens, but only five segments and a terminal one in another

specimen. The shorter fiagellmn 

 is more than half the length of 

 the longer and consists of three 

 long segments and a minute ter- 

 minal one. 



The antennae are about two- 

 fifths as long as the antennules 

 and consist of four segments ; the 

 first segment is stout and carries 

 three (perhaps four) plumose setae; the other segments are slender, 

 the second one-fourth as long as the third, which again is less than 

 haK as long as the fourth; the second and third have each a single 

 seta, and the third an apical group of very minute setae. 



The mandibles and maxillae are of normal type. The maxillula; 

 have a well-developed palp, carrying two setae. 



The first maxilliped and its branchial apparatus resemble closely 

 those of Paralam'pro'ps serratocostata as figured by Sars.
