work. His recognition of this species seems to be amply justified. The 
smaller o£ the two specimens at hand has R = 33 mm. and r=15, while 
the larger has the measurements 65 and 30 mm. respectively. Even the 
latter is only three-fourths as large as Doderlein's type. According to the 
label the smaller specimen was " dredged between Rat and Pelsart Group.-" 
It differs from the larger in the paucity of granules and pedicellarise on 
the abactinal surface, which is nearly, smooth. Even the superomarginal 
plates have very small groups of granules, especially near the interradius. 
At the base of each arm, on the carinal line, 7 mm. from centre of disk, 
is a low but conspicuous tubercle. There are two smaller tubercles near 
the anus. Similar tubercles can be seen in the larger specimen, but as 
they have not increased in size with the growth of the sea-star, they are 
no longer conspicuous among the numerous granxdes and pedicellarise with 
which the abactinal surface is covered. This larger specimen was dredged 
off Fremantle. Its colour (dry) is brown-olive, with granules, tubercles, and 
pedicellarise nearly white or at least very light brownish and the madre- 
porite chocolate-brown ; on the oral surface the granules and pedicellarise 
are so numerous and crowded that the general effect is much lighter than 
dorsally. The smaller specimen is grey-brown above and light yellowish- 
brown below. The larger specimen is very similar to specimens of 
A. ■pentagonula of the same size, but it is evidently still immature. 
Anthenea globigera. 
Dciderlein, 1915, Jahrb. Nassau. Ver. f. Naturk. Wiesbaden, Ixviii. p. 60. 
A very fine ^«i/i?)iea, taken by "shore-collecting. Wallaby Group," is 
undoubtedly to be referred to this well-marked species. It is larger than 
Doderlein's type, in which H = 59 and r = 30 mm., for U = 70 and 
r =: 34 mm. The radial series of tubercles is nearly wanting, though the 
5 primary ones are evident. Large dorsal pedicellarife are numerous and 
conspicuous. The tubercles on the marginal plates are smaller than in 
Doderlein's type. The dorsal surface is dark purple-brown, with tubercles, 
pedicellarise, and madreporite conspicuously light-coloured in contrast ; the 
oral surface is wood-brown, the tubercles, spinelets, and pedicellariifi much 
lighter. 
Feomia andamanensis. 
Koehler, 1909, 'Investigator' Ast. p. 105. 
Six specimens of a Fromia have been a source of great perplexity in the 
study of the Abrolhos sea-stars, but I have failed to find any satisfactory 
reason for not referring them to andamanensis. The unique holotype of 
that species is from the Andaman Islands, without more definite locality, 
and while it is recorded as from " 238-290 fathoms," I think there is 
undoubtedly a mistake about the depth, (,'ertainly the specimens from the
