PYCNOGONIDA. 



fath. (Wandel). Further we have it also farther south than the Ingolf-stations, viz. in the Faroe- 

 Shetland Channel, 6i"23'Lat. N. 4- 21' Long., 505 fath. (idem|. 



Distribution. This species is widely spread, as well far to the north, from the arctic North 

 America (Bell), Discovery Bay (Miers), Franz-Joseph Land (Heller), and in the Kara Sea (Hansen), as 

 also so far to the southward as 60° Lat. N. 



2. Gen. Paranymphon Caull. 

 Paranymphon Canller\-, Pycnogonides, 1896. 



Corpus glabrum. 



Processus corjjoris perlongi. 



Chelae resupinatae, subinermes. 



Palpi septem-articulati. 



Pedes oviferi octo-articulati, nngulati. 



Pedes gressorii absque vmguiculis auxiliaribus. 



The trunk smootli. 



The processes of the trunk very long. 



The chela bent backwards, the teeth weak and few. 



The palps seven-jointed. 



The o\-igerons legs eight-jointed, provided with claws. 



The ambulator}' legs without auxiliary claws. 



Caullerv, I.e. p. 361 has founded the genus on one single characteristic, viz. the number of 

 joints in the palps, which number, however, is wrongly given as 6 instead of 7. As moreover no 

 real diagnosis has been given either of the genus or the species, I have thought it necessary to give 

 such, but also to point out that, only one species of the genus being known, it will be difficult always 

 to determine, which characteristics are to be regarded as generic, and which as specific ones.
