I4 o DISCOVERY REPORTS 



panded, subcircular, hind margin entire as in the figure on plate 7, not serrate as the 

 figure of the whole animal on plate 6 seems to suggest. 



Remarks. It is but reasonable to assume that these specimens are the same as 

 Stebbing's species, although the 5th joint of gnathopod 1 and the antennae are not 

 exactly as Stebbing described them. It would seem that the antennae vary somewhat in 

 relative lengths, though Stebbing even toyed with the idea of a new genus because the 

 antennae in vallentini differed in length from those of the typical species Monoadopsis 

 longicornis. The present specimens in this respect agree with those of Monocalodes. 



Distribution. Falkland Islands, low water.

Occurrence: 1. St. 45. South Georgia. 1 $ 17 mm. 



2. St. 145. South Georgia. 2 $? 14-5 and 22 mm. 



3. St. 159. South Georgia. 2 ?? 18-19 mm. 



4. St. 167. South Orkneys. 1 <$, 1 $ 21 mm. 



5. St. 180. Palmer Archipelago (160-330 m.). 5 ?? 12-20 mm. 



6. St. 181. Palmer Archipelago. 2 <$<$ 16 and 18 mm., 8 ?$ (3 ovig.) 16-24 mm., 

 3 immat. 12-14 mm. 



7. St. 182. Palmer Archipelago. 1 $ 17 mm., 1 ? 14 mm. 



8. St. 190. Palmer Archipelago (315 m.). 2 ovig. ?? 21 mm. 



9. St. WS 25. South Georgia. 1 $ 16 mm. 



10. St. WS 33. South Georgia. 1 $ 19 mm., 1 juv. 10 mm. 



11. St. MS 66. South Georgia. 1 $ 19 mm. 



12. St. MS 67. South Georgia. 1 (J 12 mm. 



13. St. MS 71. South Georgia. 2 $? 11 and 13 mm., 2 juv. 7-8 mm. 



Remarks. The eyes are much more gibbous and prominent than in Chevreux's figure. 



The two ?? from St. 145 are pale biscuit-colour, with numerous reddish specks, 

 visible chiefly on head, side-plates 1 and 2, and on the pleon. The colour of the <$ from 

 St. 45 is given as " all body segments closely covered with small maroon chromatophores, 

 appendages pale, eye black". 



It would seem that lahillei is synonymous, showing an extreme development of the 

 dorsal "wrinkling", which is somewhat variable, as is seen in the present material, and 

 as was remarked upon by Chevreux in 1913 in comparing his specimens of calmani with 

 Walker's original description. See also Schellenberg, 1931, p. 140. 



Distribution. Ross Sea, 100 fathoms and 256-379 m. ; Marguerite Bay, 200-254 m. ; 

 South Sandwich Group, 30-50 fathoms.
