 several new Species. By George Hodge *. 



[Plates XII. & XIII.] 



No complete list of the British Pycnogons 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- 

 cuharly 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 Phoxichilidium by Mr. Gosse, and a Phoxichilidium and a 

 Nymphon by myself), no new 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, 



making in all 22 species, including the 4 which were recorded 

 in my Report of the Pycnogons obtained last year, during the

 ciation Meeting at Newcastle-on-Tyne, August 1863.
