A Remarkable Pycnogonid 
William A. Hilton 
In a collection of a thousand pycnogonids obtained at Laguna 
Beach and nearby a single specimen of the species here described was 
found. This was taken near Laguna under a stone at low tide. The 
two-jointed proboscis, the segmented body, the long tapering legs 
with their peculiar spines and hairs, these and other features were 
distinctive. 
After searching through the rather extensive literature of this 
group it was found that few species resembled this one. Epeci- 
ally was the proboscis different. The genus Ascorhynchns estab- 
lished by Sars in 1876 seems very close to it, but there are a 
number of slight differences. No species in this genus is like it. 
The genus Eiirycyde, Schodte, 1857, as described by Sars in his 
great work of 1891 seems to fit this specimen exactly. The species 
E. hispiuia Kroyer, as described and figured by Sars seems at first 
to be nearly the same as the specimen at hand, but a careful examina- 
tion shows numerous specific differences. Sars considers this E. 
hispada the only species of the genus described at that time, 1891. 
T have found no species of this genus described since. E. hispada 
Kr. has been found on the coast of Greenland, Finmark, Nordland, 
in the Kara sea; at a depth of 50 to 191 fathoms. 
Eiirycyde spiiwsa n. sp. 
Tvpe specimen — a female in the collection of Pomona College. 
Total length 3.085 mm. Extent from side to side 3.6 mm. (ob- 
tained from a preserved specimen mounted on a slide). Collected 
at low tide under a rock. Two Rock Bay, Laguna Beach, Califor- 
nia. September, 1915. 
Trunk rather broad. Lateral processes long, swollen caudally. 
Segments of trunk plainly marked from each other. Chitin thick. 
Caudal segment long slender. It projects upwards at a moderate 
angle and bears four large hairs or spines near the end, two of these 
are central, two arc more lateral.
