Nos. 78, 86, 120, 127, 131, the localities being respectively 

 lat. 33 54' 15" S., long. 25 53' 30" E., depth 57 m. ; St. 

 Francis Bay, lat. 34 3' 20" S., long. 25 10' E., dppth 62 m. ; 

 off Buffalo Bay, Cape Point Lighthouse SW. by W. 3A- miles 

 depth 58 m. ; Sebastian Bluff NW. by N. 3* miles, depth 

 55 m. ; and Sebastian Bluff WNW. 2 miles, depth 44 m. The 

 specimens sent by Dr. Gilchrist from these stations are well- 

 grown males together with females carrying numerous eggs. 

 I have not been able to detect on any the longitudinal medio- 

 dorsal row of denticles described and figured by Zirnmer as 

 beginning behind the eye-lobe and extending half the length 

 of the carapace, but in all other respects it seems impossible 

 to fix on any specific character to separate our specimens either 

 from /. africana or the earlier I. brevipes. In size, however, 

 they as a rule greatly exceed those of the earlier description. 

 A male from station 120 measures 15 mm. in length from front 

 to end of the telsonic segment, and a female from the same 

 locality is 18 mm. long. Hansen notices the extreme slender- 

 ness of this species, the uncommon length of the second joint 

 in the third rnaxillipeds, and the short stumpy structure of the 

 second leg. It is perhaps common to the genus, and is 

 certainly not confined to it, to show a sexual distinction in 

 the fourth thoracic segment. In the male the sides below 

 have a lobe produced forward into a correspondent cavity of 

 the preceding segment, whereas in the female a hind lobe 

 of the third segment is produced backward into a cavity of the 

 segment which follows. 



IPHINOE ZIMMEEI, n. sp. 

 Plate XLIV. 



The present species has at first sight some resemblance to 

 Iphinoe robasta, Hansen, from the Gulf of Guinea, but on 

 examination any close resemblance vanishes. As in that species 

 the pseudo-rostrum is short, and when slightly bent down presents 

 almost a truncate front, but there are none of the median or lateral 

 furrows which distinguish the male of 7. robusta, and the differences
