Third and fourth peraopoda as in P. HolboUi, except that 

 the latter is rather longer. 



Last peraiopoda with three shallow teeth on the hind 

 margin of the tirst joint ; second and third joints in the female 

 with long plumose setaj, remaining joints gradually decreasing 

 iu length. In the male the fourth joint has four curved 

 and blunt spines in an equidistant comb-like row on the 

 distal half of the anterior margin ; the third joint has no 

 plumose setee. 



Uropoda and telson nearly as in P. IlolboUi, but there are 

 no spines on the longer ramus of the third uropoda. 



Length 3 millim. 



This species may be at once distinguished from P/ioxo- 

 cephalus Holbolli, Leptophoxus falcatus, and the genus Har- 

 pinia by the conspicuous eyes, while the shortness of the tirst 

 four joints and the form of the hand in the gnathopods, as 

 also the characters of the last pair of pereeopoda, distinguishes 

 it from Paraphoxus oculatus and Phoxocephalus Fultoni. A 

 male and female were dredged by me off St. Peter's Port, 

 Guernsey, in 7 fathoms, on a bottom of coarse gravel, clinkers, 

 and broken shells, on April 4, 1892. I have also received a 

 male from Mr. J. T. Caiman, University College, Dundee, 

 who informs me that it was found with a few others among 

 a number of male P. Fultoni, Scott, received from Mr. D. 

 Robertson, of Cumbrae, some years ago.
