6 ALLAN HANCOCK ATLANTIC EXPEDITION REPORT 



cular aperture occupies all, or nearly all, of the distal end ; the surface 

 is supplied with somewhat faint annulations placed quite close to one 

 another. 



Distribution. — Station A42-39, 7 miles north of Margarita Island, 

 21-22 fathoms. 



Remarks. — Except in its generic characters this species has little in 

 common with any other American species, hence no suggestion can be 

 given as to its relationship. 



Genus CLYTIA 

 Glytia noliformis ( McCrady) 



Campanularia noliformis McCrady, Gymno. Charleston Har., 1858, 



p. 92. 

 Clytia noliformis Fraser, Atlantic Hyd., 1944, p. 144. 



Distribution. — Caledonia Bay, on floating sargassum ; 3 miles north 

 of Coche Island, 21-22 fathoms. 



Glytia similis, new species 

 Plate 1, Fig. 3 



Trophosome. — Clytia similis appears in a habitus of two types; 

 in the one the nutritive zooids appear individually growing directly from 

 the stolon, and in the other, at least two zooids appear in a colony, the 

 peBicel of one of them being in the nature of the stem from which pedicel 

 the other grows as a branch. The hydrotheca is large, deeply campanu- 

 late (1.0x0.35 mm), expanding but little from near the base to the 

 margin. It is shaped much like that of Gonothyraea gracilis, with the 

 teeth, 11-12, sharp and deeply cut like those in that species. The pedicel 

 varies in length from three-fourths of the length of the hydrotheca to one 

 and a half times that length ; it is closely annulated for some distance 

 from the base and much less closely annulated for a lesser distance dis- 

 tally. A colony with 2 hydrothecae is 6 mm in height, with the second- 

 ary hydrotheca and pedicel 3 mm. The annulation Is similar to that in 

 the pedicel of the solitaiy zooid. 



Gonosome. — In colonies where solitary zooids appear, the gonangia 

 grow directly from the stolon ; in colonies where 2 or more zooids appear, 

 the gonangia grow from the primary pedicel or stem. They are very 

 similar to the gonangia of Clytia johnstoni, elongated oval, truncate dis- 

 tally, and tapering to a short pedicel proximally. The surface is cor- 

 rugated, each corrugation terminating in a distinct ridge. 



Distribution. — Station A32-39. 3 miles north of Coche Island, 19- 

 33 fathoms. It was obtained as well at Cubagua Island on algae in 

 shallow water.
