2. Selaginopsis Allmant. 
1876. Selaginopsis fusca, Allman, Linn. Soc. Journ, vol. xii. p. 272, 
pl. xii. fig. 1, and pl. xix. figs. 1, 2. 
This Japanese species has similarly the hydrothece ar- 
ranged in double file on each stde (as opposed to the face) of 
the branchlets; but they are here distinctly in two lines at 
their bases as well as at their apices, the arrangement of cells 
being, as it were, that of a double Sertularia (e.g. S. absetina) ; 
instead of a double Sertularella as in the last case. 
3. Selaginopsis mirabilis (Verrill). 
18783. Diphasia mirabilis, Verrill, Amer, Journ. Science, ser. 3, vol. v. 
p. 9 (note). 
1876, Diphasia mirabilis, 8. F. Clark, in Scientific Results of Explora- 
tion of Alaska, vol. i. p. 15, pl. vii. fig. 56. 
1877. Polyserias Hincksti, Mereschkowsky, Ann. Nat. Hist. ser. 4, 
vol. xx. p. 228, pl. vi. figs. 15, 16. 
Hab. New-England coast (Verrill), Alaska (Clark), White 
Sea (Mereschkowsky). , 
Here we find the process of multiplication of cells carried 
still further, and what was in the former instances compara~ 
ble to a double Sertularian, is here equivalent to a triplicate 
Sertularian, an extra pair of hydrothece being introduced. 
The general aspect of the hydrophyton, as represented in 
fig. 15 (‘ Annals’), reminds us strikingly of that of S. fusca, 
Johnston, in mode of ramification, in general aspect of the 
branchlets, and in their great slenderness at the point of at- 
tachment to the main stem.

Cosmiide. 
105. Cosmia distincta, n. sp. 
Primaries grey, crossed by two blackish-edged white lines, 
much as in OC. affinis; an abbreviated basal white litura ; 
central area more or less clouded with ferrugimous, with a 
central brown angulated belt ; external area dusky, limited 
internally by an irregular whitish streak; a semicircular 
whitish-bordered costal brownish spot, much like that of C.
