76 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 22 



COELENTERATA 

 ALCYONARIA 



Genus DISTICHOPTILUM Verrill, 1882 



Distichoptilum verrillii Studer, 1894 

 (Plate 1, fig. 2) 



Nutting, 1909, p. 713, pi. 87, fig. 10. 



Specimens of this pennatulid alcyonarian were recovered in 3 samples 

 from San Clemente Basin, all in depths of more than 1000 fms. Identi- 

 fication was made by Dr. Frederick M. Bayer of the United States 

 National Museum, to whom we are indebted. The illustration was made 

 by Mr. Anker Petersen, from a specimen taken at Sta. 6091. 



This species was first described off western Mexico in nearly 1000 

 fms, was reported off the West Indies in more than 1500 fms (Nutting, 

 1909, p. 713), and also from off San Diego, California, in 1000 fms. 

 The present records are within the range of its known distribution and 

 in comparable depths. 



Characteristic features include the slender form of the colony, measur- 

 ing to 225 mm long. The long axis terminates in a translucent bulb at 

 the base (Plate 1, fig. 2) ; a slight thickening of the stem is visible about 

 half way along its length. The polyps are in nearly opposite to alternate 

 series, but chiefly dorsal rather than ventral, along the axis. Fresh speci- 

 mens are light flesh-colored ; the rachis is white and the basal bulb is pale 

 yellow. These colors were noted by Dr. J. Laurens Barnard, who pre- 

 pared the specimens aboard ship. 



SCYPHOZOA 

 Genus STEPHANOSCYPHUS Allman, 1874 



Stephanoscyphus simplex Kirkpatrick, 1890 

 (Plate 1, fig. 1) 

 Kramp, 1959, pp. 174-182, text-figs. 1-9, plate 1, figs. 1-11. 



Many small, cornucopianlike, horny, brown, annulated tubes were 

 taken in San Clemente and Velero Basins and San Diego trough, the 

 shallowest in 710 fms in the trough and all others in over 1000 fms. 

 They agree so closely with some described by Kramp (1959) from the 

 collections of the Danish vessel GALATHEA that they are considered 

 identical.
