202 E. W. SEXTON. 



Fam. acanthonotozomatidae. 



Gen. Iphimedia, Kathke. 



Iphimedia obesa, Eathke. 



(Stebbing (41), p. 214.) 



Station V. One specimen, nearly 12 mm. in length, several young re- 

 maining in the pouch. 



Boeck (4), p. 246, erroneously describes the maxilliped-palp as 4- 

 jointed, the 4th joint rudimentary, although in the figure (PI. XVIII. 

 fig. 11 h.) it is represented as 3-jointed. Sars gives the number of joints as 

 three, " dactylus wholly wanting " (30), p. 377. The Huxley specimen 

 agrees with Sars's figure, except that the apex of the 3rd joint is 

 truncate, not rounded. The large sensory spines on this joint are each 

 composed of a stout feathered shaft and a small endpiece, which is in- 

 serted in the cleft at the apex of the shaft. 



Recorded by Chevreux (13), p. 479, and (14) p. 63 ; and by Walker 

 (46), p. 159. Chevreux's records are from much shallower water, 

 10-50 metres. 



Fam. TRONIDAE. 



Gen. Syrrhoites, G. 0. Sars. 



Syrrhoites walkeri. Bonnier. 



(Stebbing (41), p. 281.) 



Station XII. One specimen, a large female, 9 mm. in lengtli. 



This is the first record of the species since its discovery by tlie 

 Candan Expedition in the Gulf of Gascony, 1895. 



The Huxley specimen is larger and older than the female described 

 by Bonnier (6), pp. 647-50, measuring 9 mm., as compared with the 

 " un peu moins de 7 mm." of Bonnier s largest specimen. The greater 

 age is shown by the greater number of joints in the flagella of the 

 antennae, Boniiier's female having nine in the superior tlagelluni and 

 seven in the inferior, while the Huxley specimen has eleven and nine 

 respectively. The incubatory lamellae are fully developed, no eggs re- 

 maining in the pouch. 



Gen. Syrrhoe, Goes. 



Syrrhoe affinis, Chevreux. 



1908. S. affinis, Olievreux (16), pp. 7-9, fig. 4.) 



Station IX. Two specimens, measuring 9*5 mm., ovigerous females, one 

 with eggs nearly hatched.
