COLEOPORA SERIATA, new species 



Plate 19, figs. 9-12 



Description. — The zoarium encrusts shells and especially nullipores; 

 the branches, bi to multiserial, are brown colored, narrow, linear or 

 curved. The zooecia are distinct, separated by a deep furrow, very 

 large, lageniform, terminated by a very long, smooth peristomie; 

 the frontal is quite convex and perforated by very small tremopores 

 separated by minute protuberances. The peristomice is orbicular or 

 somewhat elliptical; the aperture, buried at the bottom of a very long 

 peristomie, is orbicular and bears frequently a wide lyrule. 

 Measurements. — 



Peristomice^ -0.25-0.30 mm. Zooed JLz -=1.25-1.70 mm. 

 tip -0.30-0.40 mm. \lz =0.60-1.00 mm. 



Affinities. — The absence of crests to the tremopores, the long peris- 

 tomie and the colonies formed of multiserial branches clearly differen- 

 tiate this species from Coleopora verrucosa and C. erinacea. We have 

 not observed the ovicell. 



Biology. — The ectocyst covering the cells is colored deep brown. 

 All our specimens were dead, so that we are not sure that the example 

 from D. 5577 was really living at the great depth of 240 fathoms.

Family GALEOPSIDAE Jullien, 1903 



As now understood by us this family includes all the genera referred 

 here in our 1920 work except Semihaswellia and Tessaradoma, which 

 are now assigned to the Sclerodomidae. 



Genus GALEOPSIS Jullien, 1903 



We now know a score of species of this tropical genus and we are 

 beginning to recognize its structure. Our new observations have 

 resulted in the following conclusions.
