BARBADOS-ANTIGUA EXPEDITION 115 
very interesting Aglaophenia is allied to A. lophocarpa. It has 
septal ridges in the hydrocladia; the corbula is an elegant 
structure, long and slender, with leaves free at their edges, and 
with long spur-like nematophores. The distal ends of the 
leaves are folded over the gonangia and bear several nemato- 
phores; but there are none on the edges of the leaves except 
near the ends, in which this species differs from any other that 
Ihave seen. It was taken at Station 51, depth 33 fathoms. Still 
another Aglaophenia seems to be A. allman. A. rigida and A. 
rhynchocarpa were also secured. 
A very fine specimen of Halicornaria speciosa is from Station 
65, depth 50 fathoms. The hydrothece of this form are among 
the most graceful that I know of, the long curved mesial nema- 
tophore being the most prominent. The gonosome was present 
and consisted of top-shaped gonangia without a protective con- 
trivance of any kind. Lytocarpus was represented by a single 
specimen from Station 21, depth 60 fathoms. Many of the 
hydrocladia were greatly elongated, with their distal portions 
devoid of hydrotheez. This probably indicates that the species 
is capable of stoloniferous reproduction. But a single represen- 
tative of the genus Plumularia was found. This was P. mega- 
locephala and is from Station 65, depth 50 fathoms. The gono- 
some was present and resembled that of P. setacea. 
Among the sertularian hydroids may be noted fine colonies of 
Synthecium tubulifera. The gracefully outeurved tubular hy- 
drothece are among the largest found in the family and are 
transparent as the clearest glass. Another specimen was se- 
eured having the characteristic gonangia like minute Chinese 
lanterns growing from the lumen of the hydrotheca. There has 
been much controversy over the validity of this genus. It 
seems perfectly valid to the present writer, being well charac- 
terized by the unique feature of its gonosome. 
The campanularians were represented in the main by various 
species of Lafoecidae. A beautiful Lictorella was found at Sta- 
tion 35, depth 80 to 90 fathoms. It had a distinctly geniculate 
stem and gracefully curved tubular hydrothece. Another, 
probably new, form has a fascicled stem and tubular hydro- 
thece with a single annulation at their bases. Cryptolaria was 
represented by two species. One resembled C. pulchella, having
