THE ALOYONARIA OF PORTO RICO

a Kophobelemnon, but a critical examination showed the spicular and structural character of a 
Solanderia, to which, with some hesitation, it is here referred. It has seemed that the horny, tubular 
support is but the secretion of the colony about a foreign stem, which had either disintegrated and 
fallen away or from which the dredge had withdrawn it in the capture. In size and form the spicules 
indicate its close genetic relations with Solanderia, and in the color, texture, etc., the colony is very 
much like the previous species. With these probabilities in view the specific name crustata is here 
proposed as indicative of the habit, if such should prove characteristic of the species. 
Station 6064, Mayaguez Harbor; depth, 22 to 33 fathoms; sand and mud; taken bv dredge. 
Spicules t.uberculate, 0.18 mm.;, spiny spindle, 0.23 mm. 
Chrysog'org'ia desbonni Duchassaing & Michelotti. Plate i, figs 1 to 5. 
This beautiful colony is flabellate, usually branching in single plane. In the specimen under 
consideration there is a division near the base into two branches of about equal size. These subdivide 
and branch in a perfectly similar way, forming two parallel fan-shaped forms. In size the specimen 
measured 100 mm. in height by about 110 mm. in breadth, base not present. The axis is horny and 
somewhat calcareous, black and very hard. Ccenenchyma thin and white (alcoholic) and contains 
oblong and fusiform warty spicules. Cf. fig. Calicles rather large, somewhat scattered, and standing 
almost at right angles to the axis. Spicules, large, thorny spindle, 0.53 mm. ; irregularly warted, 0.27 
mm.; thorny, 0.20 to 0.24 mm. 
A single specimen taken by trawl from station 6070; depth, 220 to 225 fathoms; rocky bottom; 
January 21, 1899. 
Primnoa pourtalesii Verrill. Fig. D. 
Only a small fragment of a single specimen of this species is contained in the collection, but suffi- 
cient to clearly establish its identity. Specimen about 50 mm. in height, with alternating branches 
in same plane about 3 to 5 mm. apart. Only the slightest indications of the zigzag aspect of the main 
stem mentioned by Verrill, though larger specimens would probably show this more clearly. Both 
stem and branches bear calicles on opposite edges in 
close rows, slightly alternating or almost opposite. 
They are beautifully covered with series of imbri- 
cating scales, the terminal ones, eight in number, 
forming a sort of operculum, being triangular in 
shape. The color is white (alcoholic), axis light 
amber, or straw color. Spicules in Fig. I>. 
Aeanthogorgia aspera Pourtales. Plate i, figs. 6-1 2. 
In height the colony is about 300 mm. , sparingly 
and unequally branched in a somewhat flattened 
plane. Axis dark and horny. Ccenenchyma thin, 
filled with elongate, fusiform spicules which project 
from the surface, giving it a very rough appearance. 
Calyces elongate, about 2 mm. by 1.2 mm. thick, 
somewhat constricted near summit, which is enlarged 
and furnished with sharp, slender, divergent spicules. 
See plate i, figs. 6-12. Spicules, oral, 0.717 to 1.04 
mm.; stem, 0.647 to 0.68 mm.; quadripartite, 0.21 
by 0.24 mm. to 0.20 by 0.34 mm. 
A single specimen from station 6070, at a depth of 220 to 225 fathoms, from rocky bottom; taken 
by trawl, January 21, 1899. 
Paramuricea hirtaP Pourtales. Fig. E. 
In height the specimen is about 80 mm. by about 55 mm. broad, grayish white (alcoholic), 
much branched, flabellate in form, the smaller branches at various angles, surface rather rough, 
granular. Calicles rather prominent, 1 to 1.5 mm. in length by 0.75 mm. in diameter. Ccenenchyma
