'TERRA NOVA" EXPEDITION. 



" beyond all doubt." The matter cannot, perhaps, be settled without a renewed appeal 

 to the type-specimens, but the evidence available indicates that the " Discovery" and 

 " Terra Nova " specimens should be referred to A. gihhosa, and that Leionymphon 

 grande, Hodgson 1907, should be removed from the synonymy which I recently 

 (1915a, p. 314) gave for A. carol'mensis , Leach. 



Measurements, in mm. — The following measurements are taken from adult females : — 



Animothea gihhosa. Ammotliea grandis. 



Ammotliea sjnnosa (Hodgson). 



Leionymplion spinosum, Hodgson, 1907, p. 49, PI. vii, fig. 2. 

 Amniothea xj^inosa, Bouvier, 1913, p. 123. 



Occurrence. — Station 338, Entrance to McMurdo Sound, 207 fathoms ; 1$, 1 ^. 



Remarks. — This well-marked species was described by Hodgson from a single 

 female specimen, with which the two uow examined agree closely, the male differing 

 only in the structure of the ovigers. 



Ammotliea minor (Hodgson). 



Leionymphon minus, Hodgson, 1907, p. 44, PI. vi, fig. 2. 

 Ammotliea minor, Bouvier, 1913, p. 131, figs. 83, 84. 

 Ammotliea gracilipes, Bouvier, 1913, p. 132, figs. 85-87. 



Occurrence. — Station 220, off Cape Adare, 45-50 fathoms ; 1 $, 1 immature. 

 Station 340, off Granite Harbour, 160 fathoms; 1 $. Station ?, 1 ?, 3 immature. 



Reniarks. — The specimens obtained by the " Terra Nova " unc|uestiouably belong- 

 to the same species as the types of the " Discovery " collection, and, like them, agree 

 rather better with Bouvier's account of the species he describes as A. gracilipes than 

 with the immature specimen that he identifies with Hodgson's species. In the larger 

 specimens the abdomen is much elevated, the legs, if not quite so slender as in 

 Bouvier's figure of gracilipes, much more so than in that of minor, and the second coxa 

 equal in length to the sum of the other two. In the smaller specimens the projjortious
