CLADOCARPUS DISTOMUS. Lyf 
Two of the seven species (profunda and operculata) have the irregularly 
branched habit of the species of Lafoea, the form of the colony of biarmata 
is not given, and the other four have the rigid regular habit of pectinata 
and jilicula. 
The gonosome has been found in only one of these species, pectinata, 
by Pictet and Bedot, and there is some doubt as to the character of the 
structures found, as, in addition to certain gonophore-like bodies, there is a 
Coppinia cluster on the same stem. This is most beautifully figured by M. 
Bedot on Plate 5,' and he suggests of the gonophore-like bodies, “il est 
possible qu ils représentent les gonothéques d’un des sexes et la coppinie les 
gonothéques de l’autre.” 
Some of the species are closely similar, and with more material and a 
knowledge of the gonosomes in all of them there may be some rearrange- 
ment needed. They have a wide distribution in the Atlantic and Pacific 
oceans and are deep-water forms, from 35 to 500 fms.

Trophosome : — Stem compound at the base, the hydrotheca-bearing tube 
on the surface simple in about the distal third, 50 mm. in height, but imper- 
fect, the top being broken off, bearing, near the base, one branch which is 
compound in its basal half, simple in its distal half; also eight widely sepa- 
rated alternate pinnae composed of a single tube, with the stem processes of 
three other more proximal ones which had been broken off, one pinna on 
the branch, and processes of four others; pinnae divided by transverse nodes 
into long internodes, each of which bears one hydrotheca. Hydrothecae

long, tapering to the base with an outer margin, which in side view is 
slightly S-shaped, intrathecal ridge absent, margin with one, prominent 
pointed tooth and the remainder slightly uneven. Nematophores large, the 
supra-calycine tubular, extending well above the hydrothecae, with a trans- 
verse slit-like terminal orifice, and a circular lateral opening on the inner 
side near the top; the two mesial nematophores are one below the node, 
and one below the hydrotheca, the free end of the latter not reaching to the 
base of the hydrotheca ; they are stout, broad, with a wide transverse slit-
