26 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 4 



Gonosome. — None of the zooids was mature. 



Distribution. — Santa Elena Bay, 8-12 fathoms. 



These specimens seem unlike any other American species of this 

 genus but as they are immature it does not seem advisable to give them 

 a name. 



Tubularia crocea (Agassiz) 



Parypha crocea Agassiz, Contr. Nat. Hist. U.S., IV, 1862, p. 249. 



Tubularia crocea Fraser, Hyd. of Vancouver Island, 1914, p. 127. 



Distribution. — Tagus Cove, in 30 fathoms and on coral and sponges 

 at low tide; Jicaron Island, 30 fathoms. 



Tubularia integra, new species 

 Plate 5, Fig. 24 



TropJiosome. — Individual zooids growing singly, at irregular inter- 

 vals from a loosely reticulate stolon, reaching a height of 25 to 30 mm. 

 The stolon is slightly annulated but the pedicels are entirely smooth, 

 tapering slightly to a greater diameter at the base of the hydranth; 

 somewhat swollen just proximal to the constriction where the support 

 of the hydranth takes place. The basal tentacles, 25-32 in number, are 

 long and slender as compared with the proximal that are short and 

 stout for their length; they are much fewer, 8-12. 



Gonosome. — Gonophores appear on short processes, sometimes al- 

 most sessile; there are four well-separated, but very low, tentacular 

 processes. 



Distribution. — Stephens Bay, 35 fathoms; west of South Seymour 

 Island, 5 fathoms; Pacora Island, 15-25 fathoms; Medidor Island, at 

 low tide on coral. 



Tubularia multitentaculata, new species 

 Plate 6, Fig. 25 



Trophosome. — Solitary zooids are large, up to 2 cm., with a heavy 

 brown perisarc covering the pedicel except for a short distance at the 

 distal end. Hydranth large, with 20-24 long proximal tentacles and 

 very numerous, up to 100, distal tentacles. 



Gonosome. — Gonophores with a tendency to form clusters, but the 

 pedicels are short and unbranched; the radial canals show distinctly; 

 when mature, they are large, 1.3 mm. in length. The distal end is not
