EEPOET ON THE POLYZOA. 
51 
(6) Farciminaria gracilis , n. sp. (PL V. fig. 3). 
Character. — Zoarium 1 to l | inches high, branches short, slender, curved, once or 
twice forked. Zooecia 0"'05 to '06 long, slightly narrowing downwards ; upper border 
projecting, lip protruding. A globose, cup-shaped avicularium placed rather to one side, 
with a triangular obtusely pointed mandible, which is directed obliquely downwards and 
outwards. Ocecium lofty, constricted below, with an arched lower border forming a 
blunt process on either side. 
Habitat. — Station 70, lat. 38° 25' N., long. 35° 50' W., 1675 fathoms, Globigerina 
ooze. Station 122, lat. 9° 5' S., long. 34° 50' W., 32 to 400 fathoms, red mud. 
The small size and peculiarly curved, divaricate, slender branches, at once serve to 
distinguish this species. 
(7) Farciminaria delicatissima, n. sp. (PL XXXI. fig. 5). 
Character. — Zoarium from 2 to 3 inches high, composed of once or twice forked 
straight branches. Zooecia 0"'10 to *11 long, much attenuated downwards; upper 
border subcucullate. Orifice very promiuent when open ; walls exceedingly delicate and 
flexible. No avicularia. Ocecium subconical, rounded in front, enveloped above in a 
prolongation of the epitheca or epidermis ; lower border even. A long pouch distinct 
from the zooecial cavity in front of each ooecial cell. 
Habitat. — Station 13, lat. 21° 38' N., long. 44° 39' W., 1900 fathoms, Globigerina 
ooze. Station 68, lat. 38° 3' N., long. 39° 19' W., 2175 fathoms, Globigerina ooze. 
Station 64, lat. 35° 35' N., long. 50° 27' W., red clay. Station 89, lat. 22° 18' N., 
long. 22° 2' W., 2400 fathoms, Globigerina ooze. Station 106, lat. 1° 47' N., long. 24° 
26' W., 1850 fathoms, Globigerina ooze. Station 14, lat. 21° 1' N., long. 46° 29' W., 
1950 fathoms, Globigerina ooze. 
(8) Farciminaria hexagona, n. sp. (PL XIV. fig. 10, and Pl. XXXI fig. 3). 
Character. — Zoarium 7 to 8 inches high, composed of very long, straggling, straight, 
or slightly curved branches, twice furcate ; sometimes with a broad web uniting the 
branches at the bottom of a bifurcation. Zooecia in six series ; 0"'04 to '05 long., 
narrow ; w T alls very thin and transparent, angles sharp ; upper border quite level. 
Orifice small, prominent, but with a very narrow chitinous border. Ocecia ? 
Habitat. — Station 145, lat. 46° 43' S., long. 38° 4' E., 140 to 310 fathoms. Station 
196, lat. 0° 48 S., long. 126° 58' E., 825 fathoms, hard ground. Station 195, lat. 4° 21' S., 
long. 129° 7' E., 1425 fathoms, blue mud.
