PYCNOGONIDA. 



49 



The same edge is later mentioned in the same Pycnogonid by Sars, Pycnogonidea , 1891, p. 26, as an 

 undivided lamella*, cp. pi. II, fig. 2 h. The edge is undivided, but in this species and the following 

 one it is supported by a series of thickenings or ridges, running parallel and somewhat obliquely 

 from the inner side outward, comp. my fig., pi. IV, fig. 13, and with regard to the following species 

 fig. 18 and 19. 



Occurrence. The Ingolf-station 24, in the Davis Strait, 63 06' Lat. N. 56 oo' Long. W., 1199 

 fath. ; the bottom bluish-gray, soft rmid, the temperature 24- About ten specimens were taken here.

curvatse (6*?). 

 Pedes gressorii longi, articulo altero tarsali in margine interiore acie angusta, longa instructo. Unguis

The proboscis thick. 



The oculiferous tubercle high, extremely pointed, erect, a little curved, without ocelli. 



The caudal segment short, somewhat thick, obliquely erect. 



The ovigerous legs long, the terminal part with 10 to n broad, oval leaves; in the third joint is the

 bristles (3?). 

 The ambulatory legs long, the inner edge of the second tarsal joint with a long, narrow cutting blade. 



The claw large, powerful, of about three fourths of the length of the second tarsal joint, with 



slender auxiliary claws of about one fifth of the length of the claw.

With regard to the sensorium, fig. 17 a, I must refer to the foregoing. 



Occurrence. The Ingolf-station 36 gives the species as taken in the southern part of the 

 Davis Strait, 61 50' Lat. N. 56 21' Long. W., 1435 fath., the bottom gray mud, with a temperature of 

 i5. About ten specimens were taken.
