Character. — Zoarium radicate, erect or creeping, with free dichotomous branches. 
Zooecia cylindrical or subovoid, with a broad adherent base, and more or less connate 
laterally ; arranged alternately in a double series, disposed spirally, entirely or partially 
surrounding the internodes, or in a straight line parallel with the axis, or in short 
distant groups at the upper ends of the internodes.

Vallceria lendigera, Dalyell. 
Character. — Zoarium much branched, tangled, filamentous ; branches dichotomous, 
about 0‘5x0T5 mm. Zooecia subcylindrical, ovate, subcompressed, tapering gradually 
in a long neck, disposed obliquely in series of four to five pairs close below each joint or 
bifurcation, and gradually diminishing in length from below upwards. Cells sub- 
distinct, and scarcely connate. 
Habitat. — Station 36, olf Bermuda, 30 fathoms, coral. 
[British and European Seas, ubiqiie.~\ 
(2) Amathia distans, n. sp. (PI. VII. fig. 1). 
Character. — Zoarium very slender and delicate, straggling, filamentous, very regularly 
dichotomous. Internodes long, straight, rigid, thick-walled, about 0T5 mm. in diameter, 
of pretty uniform length, and each completely encircled with a spiral coil, occupying 
usually not more than the upper half of the internode, the lower portion of which is left 
bare. Zooecia ovoid or oblong, about 0'4 or 0'5 mm. by 0‘1 to 0T5 mm., distinct or not 
closely connate, with a short conical neck. 
Habitat. — Off Bahia, 10 to 20 fathoms, mud. 
This form is at once recognisable by its delicate filamentous growth, and the great 
distance between the spiral coils, giving it somewhat the aspect of Amathia lendigera. 
Another character is the comparative shortness and distinctness of the zooecia.
