8. Guernea antarctica, nov. sp. Plate XIV. 



Length of body, exclusive of the caudal seta?, about 

 1 "451X1111. 



Anterior antennae less than half as long as the body, 25- 

 jointed, joints furnished with one, or rarely two, very short 

 setae. Posterior antennae about one-third as long as the 

 anterior pair ; with one branch two-jointed, joints subequal in 

 length, and the terminal one bearing at its apex about five 

 slender setae ; secondary branch seven-jointed, the last joint 

 bearing three slender setae at its apex, and about as long as 

 the four preceding joints, each of whicli bears a single seta. 



Mandibles with a straight cutting-edge, furnished with nine 

 (or ten) small even teeth ; palp two-branched; base two-jointed, 

 the proximal joint broadening upwards and bearing four setae 

 on its outer edge ; outer branch two-jointed, proximal joint 

 broader than long, with three setae on its outer edge, distal 

 joint short with four terminal setae ; inner branch four- 

 jointed, distal joint broad, ending in three or four long setae, 

 next three joints short, subequal, the terminal ending in three 

 setae. 



Foot-jaws as in Galanus. 



In the fifth pair of legs each branch is one-jointed, the 

 outer plate having two short spines on its outer edge, three at 

 its apex, of which the inner is the longest and strongest, and 

 two short slender ones on its inner edge ; the inner branch is 

 not half as long as the outer, and bears a few very short 

 spines on its margins. 



The abdomen is only about one-third as long as the rest of 

 the body. 



The caudal segments are about equal in length to the 

 preceding segment, and are twice as long as broad. Each 

 bears four terminal setae, of which the inner three are about 

 as long as the abdomen, and the outer is barely half as long, 

 while on each margin near the extremity is a short seta.

Two male specimens of this or a closely-allied Copepod 

 occurred in the collection . They differed from the type species 

 in the following details : The body was somewhat longer than 

 in the New Zealand form, and, as se^n from the side, was 

 somewhat tumid. The central caudal seta on each side was 

 two-thirds as long as the body, whereas in my original figures 

 they appear rather short ; but 1 think this was probably due 

 to their being broken. While the second and fourth pairs of 

 feet bore on their outer branch the four pectinated spines which
