330 DISCOVERY REPORTS 



H. fernandezi, Thiele, 1905, p. 422. Skeleton arranged as in H. caruiicida. 



H. kergiielensis, Hentschel, 1914, p. 123. Skeleton as in H. cariincula. 



H. torquata, Topsent, 1917, p. 40. I have not seen a specimen of this species, but by 

 comparing Topsent 's description with a portion of the holotype of H. rubiginosa there 

 appears to be little doubt that the two species are synonymous. According to its author, 

 the spicules of H. torquata are " generalement marques pres de leur base d'un leger 

 bourrelet qui la renfle en base de subtylostyle". The same may be said of //. rubiginosa. 



H. centrotyla, Hentschel, 1914, p. 125. Skeleton as in Thieleia rubiginosa (Thiele). 



Genus Axinella, Schmidt 

 Axinella crinita, Thiele. 



A. crinita, Thiele, 1905, p. 424, fig. 46. 



Occurrence. St. WS 82: Falkland Islands, 140-144 m. 



Distribution. Calbuco, Chile. 



Genus Pseudaxinella, Thiele 

 Pseudaxinella egregia (Ridley). 



Pliatiellia egregia, Ridley, 1881, p. 114, pi. x, fig. 6; Pseudaxinella egregia, Thiele, 1905, p. 426, 

 fig- 47- 

 Occurrence. St. 6: Tristan da Cunha, 80-140 m. 



Remarks. In his original preparations I find all the spicules Ridley has described 

 with the exception of the "Setaceous acuate". This I have been quite unable to find. 

 It must be assumed, therefore, that either this particular spicule is extremely rare or that 

 Ridley himself has made some mistake about it. The longest spicules in his prepara- 

 tions do not exceed 0-9 mm. Thiele also remarks that the spicules over o-8 mm. in 

 length were very rare in his Calbuco sponge. 



The present specimens agree closely with the holotype except that the spicules are 

 more robust and the oxea much more numerous. One specimen is sub-cylindrical, 

 presumably erect, the other massive, almost pyriform. 



Distribution. Calbuco and Sandy Point (South America). 



Genus Homaxinella, Topsent 



Homaxinella supratumescens (Topsent). 



(For synonymy see Burton, 1929, p. 443.) 



Occurrence. St. 148: South Georgia, 132-148111.; St. WS62: South Georgia, 15-45 m.; St. 

 MS 14: South Georgia, 190-110 m. 



Remarks. The first specimen is quite typical in all respects. So also is the second, 

 except that it is attached at the base to the spine of an Echinodenn. The third specimen
