Remarks. — Nymphon soUtarhim is placed with those species of 

 NympJion that have auxiliary claws and in which the first tarsus 

 is considerably longer than the second. Among the species noted 

 by Bouvier (1913) and Hodgson (1907), N. solitarium most closely 

 resembles N. meridional e and N . Jdemale. It is separated from 

 these by the fact that the scape of the chelicera is shorter than the 

 proboscis. See Bouvier (1913, p. 73) on Arctic and sub-Arctic 

 species of Nymphon. 



NYMPHON TURRITUM, new species 



Figure 33, g-li 



DescTiption. — Body not so elongated as usual among members of 

 the genus; lateral processes as long as or longer than segment of 

 the body is wide, well separated. Proboscis long, cylindrical, with- 

 out markings or ridges, somewhat ventrally inclined. Cheliferi well 

 developed, the first segment or scape as long as proboscis and slightly 

 bowed outward; hand or second segment shorter and heavier than 

 first segment and inclined toward mouth, both preceding segments 

 quite well clothed with hair and occasional spines ; fingers very short 

 and stout for member of this genus ; immovable finger a little .shorter 

 than movable finger, both densely armed with long teeth along inner 

 margin. Palpi with origin lateral to cheliferi, first segment very 

 short, second and third long and slender, third a little longer than 

 second and terminating in a well-developed ventrally curving spine 

 and a circlet of hairs; segments 4 and 5 shorter, well clothed with 

 hairs. 



First segment with neck short and thick, greatly expanded at 

 distal end for attachment of cheliferi and palpi, this part being 

 heavier than any other portion of body. Eye tubercle directly dorsal 

 to anterior part of first segment, which bears ovigera, very slender, 

 tall, turret-shaped, very pointed at apex; eyes small, basal. In fe- 

 male paratype, eyes large and elongated, and eye tubercle slenderer 

 than in holotype. 



Ovigera attached directly in front of anterior pair of walking 

 legs. First segment very short, second and third a little longer and 

 heavier and almost equal in size; fourth and fifth very long and 

 nearly equal in length; sixth much shorter but longer than second 

 and third; seventh to tenth forming a curve and slenderer than 

 preceding segments ; seventh shorter than sixth and armed ventrally 

 Avith a row of about IG toothed spines; eighth a little shorter than 

 seventh, armed with about 12 spines; ninth about equal in lengtli 

 to eighth, armed ventrally with about 9 spines; tenth almost equal 

 to eiglith and ninth, armed with about 12 ventral spines; claw very 

 nearly as long as segment 10, slender, armed ventrally with spinclike 

 teetli.
