Halieutea coccinea, sp. nov. 
D. Saye An An (CxO SP. 14... WAS. 
Discriminated at once from Halieutea stellata by the less 
depressed head, the fine needle-pointed spines, which also 
extend over the under surface, and the bilobed supraoral ten- 
tacle. Head much as in H. stellata, but with its surface more 
convex from side to side and rising more from behind for- 
wards, so that anteriorly it forms a wide dome. Disk and 
body uniformly covered above and below with spines having 
stelliform bases and simple, tapering, acute points, except 
round the edge of the disk, where they are trident; those on 
the under surface are small. Skinny filaments round the 
disk and mouth few and inconspicuous. Supraoral tentacle 
with two fleshy lobes. Hyes large, their major diameter 
one ninth the disk-length. Interorbital space widest behind, 
where it is equal to two eye-lengths, slightly concave in 
front, flat behind ; its surface covered with small stelliform 
spines. No prominent supraorbital edge. Nostrils situated 
as in H. stellata, but proportionately larger. Mouth as in 
H., stellata and with similar teeth; its cleft nearly half as 
broad as the disk, its floor up to the root of the tongue 
coloured (sepia-brown in spirit). 
Other external characters as in /7, stellata. 
Colours :—‘ Dorsum bright pink, with fine black vermicular 
lines; under surface dark crimson” (Prof. Wood-Mason). 
In spirit quite white, with the dark vermicular lines showing. 
Branchial and peritoneal cavities lined with a thick, jet- 
black, velvety membrane. Intestine long and coiled. No 
pyloric ceca. 
One specimen, 72 inches long. 
Hab. Andaman Sea, 7 miles south-east by south of Ross 
Island (Middle Andaman group), in 265 fathoms. 
One more Acanthopterygian remains to be described—an 
apparently mature bathybial fish, which does not wholly con- 
form to the diagnosis of any described family of the suborder. 
In the majority of its characters it agrees with the Trachi- 
nide, differing, however, from the members of that family in 
the entire absence of teeth. It appears, in short, to be a 
toothless Trachinid. I describe it, leaving its exact deter- 
mination to more experienced ichthyologists.
