690 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 14 



diameter of the peristomes is only slightly larger, the arrangement and 

 number of the tubules and pores is the same, and the nature of the pin- 

 nules corresponds. 



It was described from the Philippines, the China Sea and Borneo.

Family Gytisidae d'Orbigny, 1854 

 Genus DISCOGYTIS d'Orbigny, 1854 



D'Orbigny (1854:1061) gave an unusually careful and full descrip- 

 tion of this genus, in which he mentioned the attached base upon which 

 rises a narrow peduncle expanding upward into a cupuliform head, the 

 whole zoarium shaped like a wine-glass ; the upper surface very concave 

 or infundibuliform at the center and the margin with numerous simple 

 or branched fascicles. He also observed and figured (Plate 798, fig. 8) 

 the unusual position of the ovicell on the under side of the cup above 

 the peduncle. Genotype, Pelagia eudesii Michelin, 1844:123. 



This genus has been known only as a fossil from the Cretaceous until 

 O'Donoghue (1926:26) described D. canadensis as a recent form from 

 British Columbia. In the Hancock Collections there are several zoaria 

 which are similar and which fill all the requirements of Discocytis. 



Discocytis californica new species 

 Plate 69, fig. 11 



The zoarium is attached by a round thin disc, from the center of 

 which rises a comparatively thin cylindrical peduncle ; at the upper end 

 this widens gradually into a funnel-shaped head or capitvdum like an 

 inverted cone, the whole structure resembling a minute and moderately 

 short-stemmed wine glass. On its upper surface the capitulum is con- 

 cave and the whole central area is occupied by rather large cancelli with 

 thick walls and rounded apertures. Around the rim of the cup the func- 

 tional tubules are arranged in short fascicles, 8 to 10 in number, com- 

 pletely connate, the apertures measuring about 0.10 mm in diameter. 

 The base and stem show no open tubules and appear as if covered by 

 a thin pellicle. The measurements of the various zoarial parts are, on
