On a neio Genus of Pycnogon. 
This paper has become much longer than was intended, 
and I must not add to it a long list of friends to whom 1 am 
indebted for assistance ; but I cannot close without specially 
thanking Dr. Hugo Eisig, the acting director of Dr. Dohrn’s 
Aquarium, whose knowledge of the locality and constant 
kindness enabled me in a short time to collect material for the 
present communication. 
XXXII.— On a new Genus of Pycnogon and a Variety of 
Pycnogonum littorale^rom Japan. By Henry H. Slater, 
B.A., F.Z.S. 
By the kindness of Dr. Gunther I have recently been enabled 
to examine all the Pycnogonoidea in the British Museum ; 
and he has also been good enough to permit me to describe 
two species from Japan, which form part of the collection. 
The first is a remarkable one allied to Zetes (Kroyer), but 
possessing distinct generic characters. It was recognized by 
Mr. Miers, of the Zoological Department, as new, and was pro¬ 
visionally named by him Parazetes , which name I gladly 
adopt. 
Parazetes, Slater, gen. nov. 
Corpus gracile. Rostrum podunculatum, ad basim valde con- 
strictum, ad apicem paulatim attenuatum. Appendices prima? 
biarticulatae, non cbeliformes; secundae 9-articulatae, pedibus 
ovigeris 10-articulatis. Segmentum primum corporis processum 
tenuem, quasi collum, usque ad rostrum antice provehens. Abdo¬ 
men clavatum. 
Body slender ; rostrum pedunculated, broad in the centre, 
gently decreasing in diameter towards its distal extremity, 
which is minutely four-cleft; first pair of appendages (maxil- 
lipeds) 2-jointed, not chelate; second pair (palpi) 9-jointed ; 
ovigerous legs 10-jointed ; first (cephalic) segment sending 
forward a long slender neck-like process towards the rostrum, 
on the middle of which the oculiferous tubercle is seated; legs 
smooth and slender. 
Parazetes auchenicus , Slater, n. sp. 
Animal slender; rostrum resembling that of Zetes (Kroyer 
in Gaim. Voy. en Scand. Lap. &c. Crust, pi. 38. fig. 1 a-g), 
fusiform ; it also hangs down in the same manner as that of 
Zetes (ib. fig. 1, b), but is distinctly four-cleft at its apex—a
