344 Mr. A. 0. Walker on Two neio 



Third and fourth perseopoda as in P. Holbolli, except that 

 the latter is rather longer. 



Last perseopoda with three shallow teeth on the hind 

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

 with long plumose setae, remaining joints gradually decreasing 

 in 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 setae. 



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

 no spines on the longer ramus of the third uropoda. 



Length 3 millim. 



This species may be at once distinguished from Phoxo- 

 cephalus Holbolli, Leptophoxus falcatus, and the genus Har- 

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

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

 also the characters of the last pair of peraeopoda, 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. 



Fam. Pardaliscidae, Boeck. 

 Halicoides, gen. nov. 



Head with a rostrum equal to half the entire head ; eyes 

 obsolete. 



Upper antenna? with no accessory appendage at the base of 

 the flagellum, but with a small one at the base of the last 

 (third) joint of the peduncle. 



Mandibles nearly as in Halice, but with the last joint of the 

 palp about two thirds the length of the second joint and more 

 slender. 



Gnathopods simple. 



First and second peraeopods with the third and fourth joints 

 expanded. 



Remaining characters as in Halice. 



Halicoides anomala, sp. n. (<J). (PI. XVI. figs. 7-18.) 



Epimeres of person small ; first three pleon-segments with 

 a small tooth at the hinder angle, fourth and fifth injured, 

 but with no appearance of dorsal teeth.
