ACRYPTOLARIA PULCHELLA (Allman)

This species should be placed in Norman's genus Acryptolaria 

 after the scheme adopted by Stechow. 12 The specimens secured by 

 the Albatross show great variation in the hydrothecae, particularly 

 in the distance between adjacent ones, but many are quite typical 

 of the species as described by Allman and the present writer. 



Gonosome. — Not present in the specimen secured. 



Locality. — Dredging station 5168, Sulu Archipelago, Tawi-Tawi 

 group, Observation Island, 4° 56' 30" N., 119° 45' 40" E.; depth, 

 80 fathoms. 



Distribution. — Hawaiian Islands (Allman, Nutting), where it is 

 a very abundant form; Japan (Stechow) ; Pacific coast off Panama 

 (Clarke).

As this appears to be the first report of this species from the 

 Philippines and as references to it are few and the original descrip- 

 tion rather scant, the following fuller description may be serviceable: 



Trophosome. — Colony 7 cm. high, spread 7^ cm., flabellate in 

 form. Main stem quite straight, fascicled, apparently without inter- 

 nodes and bearing an occasional hydrotheca ; color, reddish or orange 

 brown. Branches on opposite sides of the stem, subalternate, the 

 main ones fascicled and colored like the stem. Pinnae on opposite 

 sides of the stem and branches, subalternate in arrangement, not ordi- 

 narily divided into internodes and quite straight. Hydrothecae 

 subcylindrical, 0.75 mm. high, 0.48 mm. in diameter. They are quite 

 rigid, the inner side somewhat curved proximally while the outer 

 side is nearly straight; margin, perfectly smooth, circular, with a 

 fine annular line or marking just below. Pedicels usually of a single 

 internode or rarely of two small ones, internodes often more or less
