Peninsula). 156 fathoms. 9/3/00. \$. Sandy Point N. \ E. 

 distant 10 miles (off East London). 95 fathoms. 14/8/01. \$. 

 s.s. "Pieter Paure." (S.A.M. Nos. 150982 and 150981.) 



Kesembles rather closely A. ophthalmica (M. Edw.), which how- 

 ever has a bisinuate anterior margin to 1st peraeon segment, a larger 

 number of ilagellar joints in 1st antenna, 10 long slender spines on 

 inner margin of 4th joint of anterior peraeopods, and the telson 

 basally excavate. 



A. megalops, Norm. & Stebb., 1904, is easily distinguished by 

 having the anterior peraeopods unarmed, though otherwise very 

 similar to the present species. 



The specific name in allusion to the bead-like ornamentation of 

 the peraeon and pleon segments. 



AEGA UROTOMA, n. sp. 

 (Plate XXXII. A.) 



Exceedingly close to Ac. truncata, Richardson (1910, I.e. p. 14, 

 fig. 13). 



Body finely punctate. Head with a small median rostrum not 

 nearly as large as in Ac. truncata, eyes large, oval, their distance 

 apart equal to one-third their greatest diameter instead of one-half, 

 occupying therefore a relatively larger portion of the head. First 

 peraeon segment longer than 2nd, 3rd and 7th, but subequal to 

 4th, 5th and 6th, with its anterior margin straight not bisinuate. 

 Epimera of 2nd and 3rd segments as long as their segments, 

 postero-inferior angles rectangular, pointed, of 4th, 5th, 6th and 

 7th segments a little longer than their segments, postero-inferior 

 angles acute, pointed, each with one oblique carina on the lateral 

 surface and another where the lateral surface passes into the 

 ventral, 1st peraeon segment with a carina on lateral margin but 

 no epimeron. Lateral margins of pleon segments 1-4 with a 

 carina. Telson a little asymmetrical, with two shallow but distinct 

 hollows at base, sides straight, posterior margin slightly concave, 

 postero-lateral angles rounded. 



First antenna reaching to end of peduncle of 2nd antenna or the 

 eyes, 1st and 2nd joints dilated, but 1st longer than broad, 2nd 

 shorter than 1st, 3rd extending beyond anterior apex of 2nd joint 

 for of its length, flagellum 14-jointed. 



Second antenna with 1st, 2nd and 3rd joints subequal, 4th and 

 5th also subequal, flagellum on both sides incomplete. 



First maxilla \\ith 7 hooked spines on apex.
