﻿The Sijmpoda. 163 



trio ; on the left side a small spine above the middle appears to have 

 no counterpart on the right. 



The upper lip is emarginate. The lower lip has the lobes tipped 

 with inward projecting points. The mandibles have a powerful 

 molar and quadridentate cutting edge, accompanied on one of the 

 pair by an accessory plate slightly smaller than the principal, and 

 fourteen spines in the spine-row, of which the foremost six are 

 feathered. On the other mandible there is no accessory plate, but 

 one additional spine, the row not showing any feathering of the spines. 



The first maxillae have the usual five spines on the inner plate, 

 apparently eleven on the outer, the palp elongate; conspicuously 

 with a single but very long apical seta. 



The first maxillipeds have the broad antepenultimate joint fringed 

 with seven much-divided spines, the next joint broader than long, 

 exceeded in length by the following joint, which is greatly expanded 

 in its basal half but quite narrow in the terminal, the re-entering 

 angle of the hind margin being beset with blunt teeth. The 

 second maxillipeds are slender throughout, the second joint 

 elongate, the third short, scarcely forming a complete ring. The 

 third maxillipeds have the second joint curved, not apically widened 

 or produced, longer than the five remaining joints combined, of 

 which the fifth is the longest, the seventh short and narrow ; the 

 exopod is slender. The mutilated first peraeopod was probably of 

 considerable length, the second is slender, with second joint not 

 quite so long as the five following joints combined, among which the 

 well-spined fifth is longer than the short sixth together with the 

 needle-like seventh ; the exopod is smaller than that of the larger 

 first peraBopod. The third and fourth peraeopods are much shorter 

 than the second, the second joint longer than the rest combined, and 

 carrying near its origin a microscopic two-jointed exopod ; the fourth 

 joint about equals the fifth and sixth together, both of which carry 

 long apical setae with annulated terminals; the seventh joint is 

 almost spine-like but not very sharply pointed. Of fifth perteopods 

 no trace could be discerned. 



The uropods have serrulate margins ; the endopod, four-fifths the 

 length of the peduncle, has a first joint about twice as long as the 

 two following joints combined, the second being a little longer than 

 the third, the spines on the inner margin being respectively ten 

 three, and one ; the exopod, which reaches nearly to the middle of 

 the third joint of the endopod, has seta-like spines on both margins. 



Length of the specimen, 12 mm.
