﻿CKUSTACIvA MAI.ACOSTRACA. II. j^ 



Too;etlier with tlie s])ociiiicii described a ver\- \(iuii.i:i spcciuKii, measurin<^- onlv 5.7 nun. and 

 Willi scveiitli pair of tlioracic le^s not developed, wa.s taken, ll sliow.s .several pecnliarities dne to 

 it.s very youn<^- age, and among these one may be pointed out, vi/. thai the lower margin (.if the sixth 

 joint of second leg.s has onl\- 5 spine.s; besides it has a s]Mne at the lower distal angle of fourth joint 

 of the same leg.s, l)ul this feature may be interpreted as \ariation. 



Occurrence: The 'Ingolf" has captured this species at a single station. 



Denmark .Strait: vSt. 10: Lat. 64° 24' X., Long. 28'' 50' \V., 7SS fm., temjx 3.5 ; 1 sul)adult and i very 



yoiuig specimen. 



Besides the "Valorous" took the species at the following ])lace. 



vSouth of Davis Strait: Lat. 59° 10' N., Long. 30'=' 26' W., 1750 fni. 



Distribution. According to the English authors quoted this species was taken b\- the 

 ■'Valorou.s" at two stations situated considerably vSouth of the Denmark .Strait, vix..: Lat. 56 11' X., 

 Long. 37^41' W., 1450 fm., and Lat. 55" 10' X., Long. 25" 58' W.. 17S5 fm. 



5. Apseudes gracillimus u. sp. 

 (PI. I, fig.s. 4a — 4e). 



Subadult Female. Body and appendages still more slender than in A. Qraci/is. — Cephalo- 

 thora.x nearly as in that species, but the eye-lobes more priidueed. The carapace without trans\'erse 

 furrow. 



The anteunuke (fig. 4a) as long as the carajiace and the two anterior free segments combined; 

 first joint slender, about three times as long as the second, without serration on the inner nuirgin. 

 Outer flagellum 17-jointed, about as long as the peduncle and more than two and a half times as 

 long as the 4-jointed flagellum. — The antenna; almost as long as the autennular peduncles; flagellum 

 S-jointed; the squama reaches beyond the end of the penultimate joint of the flagellar peduncle. 



The chelipeds \ev\ slender (fig. 4c) and their joints without sjiines or serration on the lower 

 (posterior) margin. vSecoud joint is considerably curved, long, only a little shorter than the carpu.s, 

 five times as long as broad; carpus with the lower margin only somewhat less than twice as long- 

 as that of the ischium. Chela four times as long as broad, with the ]iosterior margin \'erv concave; 

 the movable finger twice as long as the front margin of the hand and considerably longer than the 

 fixed finger, which has about 4 setie along the distal half of its incisi\e uuu'gin Init no serration or 

 setigerous area. 



Second thoracic segment (fig. 4a) has the first joint of the legs triangular with the front 

 margin nearh- trans\-erse and o\\\x the termiiurl angle produced slightK' forwards as an acute denticle. 

 The four posterior segments ha\e the lateral processes consideral)l> produced, distalh' slender, acute, 

 and no produced angles from their proximal jiart; the ]irocesses on the lower surface of the segments 

 cons])icuous or even rather long. — Second pair of legs (fig. .|d) slender, second joint with a spine on 

 the lower distal angle; fourth joint consiiicuouslx- longer than the sum of the two following joints 

 and with a s])ine on the lower distal angle; fifth joint about half as long again as broad, slightly 

 longer tluui the sixth, with a terminal siiine abo\-e and two sjiines on the lower margin; sixth joint
