.\o. 1658. ALCYONARTA OF THE CALIFORNIAX COAST— NUTTING. 721 



PSAMMOGORGIA TORREYI, new species. 

 Plate LXXXIX, figs. 1 and 2; Plate XO, fig. 5. 



Colony strictly flabelliform, the branches frequently anastomosing, 

 150 mm. lugh by 168 mm. broad. Main stem giving forth branches 

 on opposite sides separated by about 7 mm. on the average. The 

 whole forms a loose reticulation, almost exactly such as is found in 

 the genus Leptogorgia. 



The calyces are in the form of truncated cones about 1.5 mm. high, 

 and the same in breadth at the base. They are distributed on all 

 sides of the branches about 2.5 mm. apart. In front view they 

 appear to have the arrangement found in the Gorgonidse — that is, 

 two opposite rows of calyces — but a closer examination shows the 

 arrangement described above. 



The spicules are warty spindles, those on the stem and branches 

 being smaller than those on the calj^ces and polyps. The largest 

 appear to be the ones in the polyp walls and basal parts of the ten- 

 tacles, where they are large, warty, and fusiform, sometimes curved, 

 arranged longitudinally and extend downward in meridianal bands 

 to near the base of the polyps. Occasional club-shaped spicules are 

 seen, but nearly all are of the warty fusiform type. 



Color. — Dark, purplish red throughout. Many of them are almost 

 black, in alcohol. 



Type-specimen. — Cat. No. 25433, U.S.N.M. 



Distribution. — Station 4514, Point Pinos hght-house S. 39 °E. 10.7 

 miles, 524 fathoms; Station 4530, Point Pinos light-house S. 78° E. 

 6.8 miles, 26-28 fathoms (type-locality); Station 4537, Point Pinos 

 Hght-house S. 74° E. 7.4 miles, 1062 fathoms; Station 4546, Point 

 Pinos light-house S. 46° E. 8.4 miles, 849 fathoms. All of these sta- 

 tions are in Monterey Bay. 



Named for Dr. Harry B. Torrey, University of California. 



PSAMMOGORGIA SPAULDINGI, new species. 



Plate LXXXVIII, figs. 3 and 4; Plate XC, fig. 7. 



Colony flabellate in form; branches round in section. The manner 

 of ramification is shown well in the photograph. (Plate LXXXVITI, 

 fig. 3.) 



Calyces scattered closely and evenly over the surface, in the form 

 of very low verrucas which are scarcely raised above the general sur- 

 face of the colonj^. 



Polyps completely retractile, with but few spicules and these 

 tending to a longitudinal arrangement in the body walls in eight rows. 

 These rows sometimes extend part way up the outer sides of the 

 tentacles.
