in some cases the mode of growth of the genera Cornularia and 
Telesto are combined in the same specimen, the colony starting in 
the primitive way on a sponge spicule and giving off branches which 
themselves branch like 7’edesto colonies. Several cases were found in 
which a number of the sponge spicules 7 or 8 inches long are involved 
in one mass by anastomoses of the branching polyps. The branch- 
ing forms attain a height of 50 to 100 mm. 
The calyces vary enormously in size, some being 10 mm. in height 
and 1 mm. in diamenter, while others are less than 2 mm. high. Their 
_ diameter is fairly constant. 
The calycular walls are marked by eight longitudinal coste and 
terminate distally in an eight-rayed rosette. The polyps are com- 
pletely retractile. 
The spicules are stout warty spindles and clubs, the verruce being 
very thickly crowded. 
The color 1s hght brown, sometimes yellowish. 
Type.—Cat. No. 22574 U.S.N.M., Albatross Station 3910, north 
coast of Molokai, 337 fathoms. 
Distribution —Between the islands of Molokai and Maui; Station 
3865, 265-283 fathoms (Cat. No. 22572, U.S.N.M.) ; Station 3883, 277- 
284 fathoms. 
North coast of Molokai: Station 3910, 311-837 fathoms (Cat. No. 
99574, U.S.N.M.); Station 3911, 224-337 fathoms (Cat. No. 22571, 
U.S.N.M.); Station 3914, 289-292 fathoms (Cat. No. 25351, 
U.S.N.M.). 
CLAVULARIA CORRUGATA, new species. 
Plate XLI, fig. 2 
The usually somewhat distant polyps are connected by band-lke 
solenia that in places expand into lobular masses from which one or 
two polyps spring. Polyps cylindrical, 2 to 4 mm. high, slightly ex- 
panded basally, walls strongly grooved longitudinally, there being 
eight grooves and corresponding coste. ‘The distal part of the walls 
1s neornermeneally corrugated, so that the corrugations and grooves 
together cut up the sarrace into a regular series of squarish madtrlles 
Dist end forming an eight-rayed rosette over the retracted 
tentacles. : 
Spicules.—Stout warty spindles, shorter in proportion to length 
than in other species of the genus, packing the walls of the solenia 
and polyps. In the polyp walls they have no regular disposition, but 
seem to be crossed in almost every direction. They seem to be absent 
from the tentacles. 
Color.—Very light brown, almost white in alcohol.
