XITI.—List of the British Pycnogonoidea, with Descriptions of 
several new Species. By Grorncr Honce*. 
[Plates XII. & XIII. ] 
No complete list of the British Pyenogons has appeared, and 
such information as we possess is scanty and scattered. It is 
difficult to account for this neglect, as these animals possess 
considerable interest, both in their life-history and their pe- 
culiarly degraded physiological features. 
An examination of such records as I have been able to consult 
has enabled me to compile a list of twenty-two species—the 
total number recorded as British. With two exceptions (that of 
a Phoxichihdium by Mr. Gosse, and a Phozichilidium and a 
Nymphon by myself), no uew species have been published since 
Harry Goodsir’s and Dr. Johnston’s time: the former described 
seven species, principally from the Frith of Forth ; it is possible, 
however, that two or three of them might not sustain a very 
critical examination. The list, as it now stands, contains 
13 species of Nymphon, 
2 Ps Pallene, 
4, a Phoxichilidium, 
I 14 Pasithoé, 
1 Phoxichilus, 
1 ibe Pycnogonum,

making in all 22 species, including the 4 which were recorded 
in my Report of the Pyenogons obtained last year, during the
