MARINE AND FISHERIES 



6-7 EDWARD VII., A. 1907 



FAMILY : LOXOSOMIDiE. 



Loxosoma singulare, Keferstein. — Two specimens were found on Schizoporella, 

 Both have two buds of different sizes on each side. The stalk is about one-half the 

 length of the body, transversely marked, but the expanded disk below is hid from sight. 

 It only varies from Hinck's description by having eight tentacles in one specimen. 

 The number in the other could not be counted. 



Unidentified. — A specimen was found on a stone taken by the trawler Active. It 

 formed a very small, white, encrusting mass; the zooecia are arranged in very irre- 

 gular order and their boundaries are not distinct; the orifice is arched above and con- 

 vex below, due to a tubercle arising just below the orifice; this tubercle has two 

 lateral wing-like outgrowths below, and in this way forms a crescent-shaped body on the 

 front surface of the zocecium ; dim radial lines pass out from this to the margin ; two 

 spines arise from the upper side of the orifice. Many have globular ooecia above, and 

 on these the spines are absent. 



Another species was found on a stone and on the shell of Balanus taken by trawl 

 of the Active. The zoarium is encrusting and of a greenish colour; zooecia are of 

 average size, very plainly marked off from one another and of irregular and various 

 shapes, the whole surface is flat and covered with very large punctures giving: it a 

 reticulated appearance. The orifice is not terminal but at the upper end, not projecting, 

 and almost perfectly orbicular; some have two lateral denticles near the lower edge; 

 directly below the orifice is an avicularium with pointed mandible running nearly 

 horizontal, or obliquely upward.
