216 CANON A. M. NOKMAN ON THE PODOSOMATA 



N.E. America, as above, in 85-115 fathoms {Wilson and Hoek) ; off west 

 coast o£ Norway and eastwards as far as Vardo, in 40-191 fathoms (Sars) ; 

 Davis Straii and Denmark Strait, in 315-582 fathoms {Meinert) ; Newfound- 

 land (Topsent). 



17. Nymphon stenochbir, sp. n. (PI. 30. figs. 1-9.) 



Body slender (fig. 1), smooth, lateral processes widely separated, longer 

 than the trunk is broad. Cephalic segment subequal in length to the three 

 posterior segments, neck not slender, widening in front, where the segment 

 is moderately broad ; caudal segment scarcely as long as the lateral processes. 

 Oculiferous tubercle (fig. 2) low, truncate above, the angles slightly pro- 

 jecting. Proboscis long, narrow, distally rounded, nearly equal in length to 

 the cephalic segment. Chelifori (figs. 4, 5) slender, with a remarkably 

 slender hand; hand not much shorter than the scape; palm of nearly the 

 same breadth throughout, more than twice as long as the very small and 

 delicate fingers, which are gently bent. Palpi (fig. 3) slender, second and 

 third joints subequal, and the terminal rather longer than the penultimate. 

 False legs (fig. 8) greatly produced, much longer than the body ; spines 

 (fig. 9) somewhat elongated, with marginal teeth small and subequal. Ambu- 

 latory legs extremely slender, very smooth, with only scattered minute 

 spinules, except at termination of tarsus ; length of fore leg 21*5 mm., made 

 up as follows : three coxal joints combined 2"5 mm. ; femoral and first tibial 

 ■each 5 mm., second tibial 7 mm. ; tarsal and propodal (fig. 6) each 1 mm. ; 

 propodos (fig. 7) six times as long as broad, bearing on basal half four or 

 five spines, each of which is larger than the preceding, beyond this the palm 

 bears numerous spines of small size ; the claw is slender, but more than half 

 as long as the palm, the secondary claws are quite rudimentary, not larger 

 in size than the spines at the end of the propodos. Length of body 4*75 mm., 

 of proboscis 1*5 mm. 



This is a strongly characterized species, and taking jointly into consideration 

 the characters of chelifori, spines of false legs, and the propodos of ambulatory 

 legs, with the very minute auxiliary claws, it is difficult to say what described 

 form is its nearest ally. 



A single specimen was taken by the ' Porcupine,' 1869, in the Faroe 

 Channel, Stat. 64, lat. 61° 21' N., long. 3° 44' W., in 640 iathoms.

A single specimen only known, taken by the ' Ingolf ' Expedition between 

 the Faroe Isles and Iceland, lat. 63° 4' N., long. 9° 22' W., in 262 fathoms
