102 DISCOVERY REPORTS 



Peraeopods i and 2, 4th joint stout as in villosa. Peraeopod 3, 2nd joint pyriform, 

 anterior margin straight, with a few long setae, posterior margin gently convex, with 

 minute setules, 4th and 5th joints nearly as villosa. Peraeopod 4, 2nd joint stout, 

 anterior margin angularly rounded, strongly setose, especially distally where the setae 

 are plumose and form a thick fringe, hind margin slightly concave in $, straight in g, 

 with a small rounded lobe distally. Peraeopod 5, 2nd joint almost subcircularly ex- 

 panded, extending to end of 4th joint, margin shallowly notched, 3rd joint somewhat 

 lobed on anterior apex, 4th with anterior margin convex, hind apex produced in a short 

 acute lobe.

Uropod 2, peduncle fringed with upstanding spines on upper margin. Uropod 3, 

 peduncle with a half circlet of spines around the lower apex, inner ramus two-thirds 

 length of outer in $, in £ rami subequal, much enlarged, with long plumose setae. 



Remarks. Stebbing has recorded the Australian Pontharpinia rostrata (Dana) from 

 the Falkland Islands (1914, p. 357), but the present species will not fit in with his 1906 

 diagnosis as regards the maxilliped, gnathopods and 3rd~5th peraeopods. The cha- 

 racters of peraeopods 3-5 also differentiate it from the West Australian specimen which 

 Tattersall referred to villosa. 



It bears a close resemblance to Paraphoxas pyripes, Brnrd. (1930, p. 332, fig. 10), as 

 regards peraeopods 3-5, though the postero-inferior angle of pleon segment 3 is quad- 

 rate in the latter; the present form, however, has a 2-jointed palp on maxilla 1. 



The S was caught near the surface in a night haul. 



The specific name refers to the oblique row of setae on the epimeron of pleon 

 segment 3.
