Dr. Mcissm-r has suggested that A. neglecla, which I descrilied at the same time 

 as A. brandti, is the same species. I think he is right; A. belli of Prof. Studer and 

 .-1. ffl&merata of Sladen appear to be also synonymous ; with regard to the first three- 

 Prof. Perrier suggested the same view in 1891. 



My species were described on pp. 91 and 94 of the Proc. Zool. Soc. for 1881 ; 

 Dr. Moaner's synonymy will be found on p. 7 of the Ergeb. Hamburg Magalhan. 

 Snmmelreise, Lief. vii. (1904). I suggested in the report on the 'Southern Cross' 

 collections (p. 215) that the species was circumpolar in its distribution, and so it 

 certainly is. 



A large number of specimens were collected; the largest, from 4-10 fms. 

 McMurdo Bay, was the " mother of a number of young after capture " * ; and some other 

 large specimens were taken at No. 3 hole, and some smaller at No. 11. Flagon Point 

 (10-20 fins.), Cape Wadsworth, and Hut Point also yielded examples ; the large; 

 examples marked 48 and 49 are only said to be from Winter Quarters. 



From 100 fms. (East end of Barrier) and 130 fms. (No. 2) specimens were 

 collected which, but for the formidable synonymy of the species, I should be inclined to 

 regard as distinct 



A.STERIAS LONOSTAFFI. 



This fine species is represented by a single specimen, which presents well-marked 

 features. I name it after the generous friend of science whose contribution to the 

 funds of the Royal Geographical Society made the voyage of the ' Discovery ' 

 possible. 



A large stout form with R about equal to 3 r ; the whole of the dorsal surface is 

 uniformly and densely covered with paxilliform spines of some size. The madreporitc is 

 of moderate size ; the podia are enormous, the adambulacral spines are long, 

 cylindrical, blunt at the tip, so irregularly set that it is difficult to say whether there 

 are two or three rows ; beyond them there are shorter and more delicate, but otherwise 

 similar cylindrical spines very closely set ; there are two quite well-marked seta of 

 marginal plates ; the inferomarginals are very narrow in the angle of the arm, while 

 the superomarginals in the same region are very short ; both sets are covered with 

 coarse granules, among which no pedicellariae are to be detected. The podia within 

 the oral circlet are of enormous size. It = 210 ; r = 70.

As there is only a single specimen, no comparisons arc possible ; but it may be
