REPORT OX THE POLYZOA.

(6) Salicornaria dubici, n. sp. (PL XII. fig. 2). 
Character. — Zoarium from 1 to 2 inches high, slender, dichotomous, divaricate ; inter- 
nodes pretty equal; joints nodular. Areas hexagonal; interior ridges strong, meeting above 
and below so as to circumscribe an oval space ; surface granular. Orifice subcrescentic. 
Operculum subcrescentic or semicircular, O'^OOG x '0035- 
•0040. Avicularia vicarious ; mandible spear-shaped, 
with an incurved acuminate point, 0 //- 010 x '006. 
Habitat. — Station 320, lat. 37° 17' S., long. 53° 52' 
W., 600 fathoms, green sand. 
Allied to Salicornaria malvinensis in the characters 
of the avicularian mandible, but differing in the uni- 
formly granular surface and the strongly developed 
interior ridges on the front. The operculum also is more strictly semicircular, instead of 
sub-elliptical as in Salicornaria mcdvinensis, and the chitinous lateral supports in the 
operculum are furcate, and not continued across as in Salicornaria malvinensis. The 
mandible also is smaller and slenderer. It might probably, however, be regarded as a 
variety of this species.
