Mr H. Goodsir on some New Species of Pycnogonide. 137 
Genus II. Pallene (Johnston). 
Species 2, Pallene circularis (Mihi). Body almost circular, 
from a sinuated ridge which surrounds it, and covers the 
origins of the legs, extremely rough and spiney ; two ti- 
bial joints with three rows of strong hairs on the upper 
surface ; auxiliary claws obsolete ; abdomen very promi- 
nent and pointed. 
The body and legs are covered with hairs, which are scat- 
tered irregularly over it, except on the two tibial joints, where 
they are arranged in three rows along the upper surface. The 
rostrum is as long as the first joint of the mandibles. The 
first joint of the body is very short, so that the rostrum, man- 
dibles, and first pair of legs, are inserted close to one another. 
The body surrounded by a spiny sinuated ridge, which covers 
the insertions of the legs. The oculiferous tubercles with 
eyes, obtuse, black, shining, and placed in a quadrate form. 
The abdomen erect, pointed, and very prominent. Body one 
line in length; span of the legs two lines; colour dark straw, 
Hab. Firth of Forth. 
For the animal which shall be presently described, [ have 
found it necessary to establish another genus. The animal is 
remarkable, inasmuch as it forms a connecting link between 
the non-palpate and palpate genera of this order, 
Genus III. Pephredo.* 
Rostrum short, cylindric; palpi 3-jointed, as long as the 
rostrum ; oviferous legs 6-jointed ; first tarsal joint minute ; 
no auxiliary claws. 
Species 3. Pephredo hirsuta (mihi). Animal robust, opaque ; 
rostrum as long as first joint of mandibles; palpi with a 
bush at the extremity ; thigh not so long as the first tibial 
joint; abdomen short and pointed. 
The animal is of a dark straw-colour. The rostrum cylin- 
dric. The three coxal joints are equal, and as long as the 
thigh-joint. The oculiferous tubercle is obtuse, and situated 
a little before the insertion of the anterior pair of legs: the 
eyes obscure. The articulations of the body are very narrow,
