﻿COPHI'ODA 220 



fc?. Size of male was 6-5 nun.; anterinr division 5(17 nnn.; urosome 1-43 mm. 



The body is more slender than in the female; the head shows trace of a crista, especially in 

 dorsal view. The lateral corners are rounded and ])os.sess a small, well marked tooth. 



The abdonini is fairly slender (PI. \'\\ Y\>^. (^\^) and is. as seen in figure, be.set with hairy .spots. 

 The comparative leni^th of the first four abdominal somites and the furcal branches is 25, 55, 45, 

 28 and 15. 



The aiitciintihn- extend about to the end of the body; the pro.\iinal 7 .seg^ments are more 

 powerful than in the female. The .segments 8^9 to 13 are posteriorly indistinctly .separated, as the 

 articular membrane is sometimes missing; the segments 20 and _>r are, on the right side, partly fused; 

 the appendages are .scarcely different from the male of C. chrlifrr. The (iiilrmiar .scarceh' differ from 

 those of the female, but the inaiidihiilac differ by the wide third basijiodite with three rather short 

 inner setae; the maxillnlaf are more soft-skinned than in the female; the Li i has S short .setae, but 

 the number of setae is in other respects like that of the female. The iiiaxillar (fig. 6 c) is a soft-skinned 

 organ of .somewhat .similar shajK- to that of the female; the number of setae in the lobes is seen in figure; 

 the endopodite has 7 sensory setae, differing from rather clumsy ones ba.sallx to more slender ones distallv. 



The )iiaxillipcds are distinctly more robust than in the females; the comparative lengtli between 

 the main divisions is 34, 34 and 15, the setae of the second basipodite, especially the sen.sory one in 

 the middle, are less developed; the strong curved setae of the eudojKxlite are represented by rather 

 weak setae. 



The Jialatory legs are scarcely different from those of the female. Tlie Hftli pair of legs extends 

 almost to the end of the abdomen. The right leg is much shorter than the two fir.st segments in the 

 left leg (cf. PI. VII fig. 6 b), and it forms an outward convexit\-; the outer margin of the second seg- 

 ment is slightly convex, and somewhat spinous; the third segment is indistinctly divided into two 

 parts, and has at least a terminal and an outer rather weak spine as well as a number of stiff hairs 

 terminally on the posterior surface. The Irfl leg has two long cyliudric basal segments, of which tlie 

 distal one is much the longer; the second segment is convex outwards, and here possesses terminally 

 aliout 7 stiff hairs. The exopodite consists of three segments, decreasing in length as well as in 

 thickness from the first towards the third; the third segment (PI. VHI fig. 17 e) is somewhat attenuated 

 and hair}', and is in possesion of a short terminal spine. 



The epistoiiia (PI. \'III fig. 17 c) is well developed, with two rows of long setae; the labntiii proper 

 has, anteriorly, a well developed projection, but is posteriori)- r.ather soft-skinned, with undulated lines 

 in the cliitiu; anteriorly 2—4 rows of long bristles are found; posteriori)', rows (.if short bristles were 

 observed; the marginal row of hairs was apparenth' wanting. The cvv?/ surface of the labrnm is not un- 

 like that of the female, but the granulation in front is wanting; three well separated lateral groups 

 of hairs were found on each side. In the middle, just behind the third median circular spot ^i single 

 transverse group of short l^ristles was found. In front of a well de\'eIoped srrriila o-dciitafa with 

 short teeth, a median elongated grouj) with two lougiltuliual rows and, lateral!)', a single conxex row 

 were found. The labial lobes are well developed, with short marginal bristles; between the lobes a 

 small pointed process is found on each side.
