18 BULLETIN OF THE 
often largely destitute of spicula between the calicles when rubbed; in many 
parts only a few scattered, small, oblong and fusiform, blunt, warted spicula 
are found, here and there, but in other places it is covered with smaller and 
larger oblong spicula, intermingled. Color in alcohol, yellowish brown. 
Height of the largest example, 230 mm.; length of calicles, 5 mm.; diameter, 
1.5 to 2 mm.; diameter of axis, 1 mm. 
The following specimens were dredged by the Blake, 1878-80. 
Station. Fathoms. Locality. Specimens. 
205 334 Off Martinique 1 
288 399 Off Barbados 1 
A specimen was also dredged by Mr. Pourtales, on the “ Bache,” March 4, 
1869, first haul, in 450 fathoms. 
Lepidisis VerRILt, gen. nov. 
Axis with long, tubular, calcareous joints alternating with short horny ones; 
simple or branched, the branches, when present, arising from the horny joints. 
Base divided into long, irregular, flat lobes. Ccenenchyma thin, with an exter- 
nal layer of small, oblong, scale-like spicula, sometimes with a few fusiform 
spicula beneath them, especially around the calicles. 
The calicles are large and elongated; the margin is armed by about eight 
long, spiniform, projecting spicula, alternating with the tentacles; their sides 
are filled with large, fusiform spicula, which are more or less covered exter- . 
nally by small, oblong, scale-like ones, like those of the cenenchyma. Tenta- 
cles filled with numerous, small, oblong, blunt spicula. 
This genus is closely allied to Acanella, differing only in having the external 
layer of small scale-like spicula, both in the cenenchyma and on the calicles.

Two specimens are in the collection of 1880, both unbranched, but both are 
broken. One (see Plate IV. fig. 1), from Station 308, has the basal processes. 
The other, which is incomplete at both ends, is a simple stem over a foot 
(160 mm.) long, and about 1.5 to 2mm. in diameter. The white calcareous 
joints, except near the base, are long (45 to 55 mm.) and hollow; the brown 
horny joints are short (1 to 2mm.); the coenenchyma is very thin, filled with 
small, oblong, blunt, flat or scale-like spicula, with some longer fusiform ones 
around the calicles, and a few scattered ones of the same kind. The calicles 
are few, distant, long (6 to 8 mm.), clavate, slender at base, enlarging toward 
the summit, which is expanded at the end (2.5 mm.), and armed usually with 
eight long and large spine-like or fusiform spicula, which project in a circle 
around the margin, and run back nearly the whole length of the calicles. 
These are intermixed with and surrounded by numerous smaller and more
