Miscellaneous. 67 
spines standing side by side, which form the second row outside the 
furrow. The colour is orange-yellow, with an intensely red eye 
at the end of each arm. 
2. Solaster glacialis, also described as a new species, is known 
only by a single specimen dredged in N. lat. 72° 27', KE. long. 20° 
51’, at a depth of 191 fathoms, on a bottom of sandy mud. Tem- 
perature 3°°5 C. (38°3 F.). Its character is given as follows :— 
Body 7-armed. Proportion of the smaller and greater radius as 
1:3. Paxille on the back rather scattered, forming regular series 
on the arms. Interbrachial spaces beset with isolated spines, other- 
wise naked. A row of spines along the ambulacral groove. From 
every ambulacral piece there issue inwards towards the furrow from 
three to five longitudinally arranged spines, and outside the furrow 
a similar number of transversely arranged spines. There are twenty- 
eight small ventral marginal plates, bearing penicilliform paxille. 
The back is dark red, the ventral surface white. 
3. Asterina tumida, Stuxberg—Stuxberg’s Solaster tumidus, de- 
scribed in 1878 from specimens from Novaia Zemlia, was taken at 
two stations, in N. lat. 67° 24’ and 74° 54’, E. long. 8° 58’ and 14° 
53’ respectively, at depths of 452 and 658 fathoms, in water of a 
temperature below 32° F. Stuxberg’s largest specimen measured 
25 millim. across; and its larger radius was 14-15 millim. The 
expedition obtained one specimen measuring 75 millims. across, with 
a greater radius of 40 millim. The authors figure. this starfish, 
which, however, they remove from Solaster and refer to Asterina, 
although only provisionally, as it differs from that genus in the 
dermal skeleton, which does not present the peculiar arrangement of 
the calcareous plates in the dorsal surface, in the great abundance 
of tentacular pores (which are distributed over the whole dorsal 
surface right to the margins both on the arms and the disk), and 
also in the concealed marginal plates and their form. 
4, Asterina tumida, var. tuberculata.—A. starfish, about which the 
authors are in doubt whether to treat it as a distinct species or as a 
strongly marked variety of the preceding, is described by them under 
the above name. Specimens were taken at two stations, respectively 
in 76° 22' and 80° N. lat., and 17° 13’ and 8° 15’ E. long., at depths 
of 146 and 260 fathoms, with a bottom temperature of 30°-34°F. The 
colour, which in A. twmida is tile-red above, white with a yellowish 
tinge beneath, in the variety is yellowish red with pale yellow spots on 
the back and yellow on the lower surface ; the madreporic plate and 
the anus are straw-yellow, and the eyes at the extremity of the 
arms orange-red instead of deepred. There are five arms, which are 
longer and narrower than in the type form. The proportion of the 
radii isas 1:2. The back is convex, the lower surface flat. On the 
back, besides the paxille, there are many separate round tubercles, 
closer together on the arms than on the disk. The madreporic 
plate is nearly round, nearly equidistant from the angle of the arms 
and the subcentral anus, but rather nearer the former; the ambu- 
lacral furrow has three rows of spines, one of which turns in to- 
wards the furrow ; the margin is pretty strongly marked, and formed
