HYDROCORALS OF THE NORTH PACIFIC — FISHER 535 



Specimens examintd.— The type and several small fragments from 

 another male colony; two female fragments. 



Remarks. — Although this species is in the same section of the genus 

 as C. pudica Mihie Edwards and Haime (not Moseley) the two are 

 entirely different. I have specimens of C. pudica (pi. 64, fig. 1) taken 

 by the Albatross at station 5423, Sulu Sea, 508 fathoms, gray mud and 

 coral sand, bottom temperature 49.8° F. The colony is delicate, with 

 longitudmally striated stems, and many of the cyclosystems are sup- 

 ported by relatively long slender pedicels. The cyclosystems are 1 to 

 1.3 mm broad, have about 15 dactylopores, and the lid stands higher 

 above the cyclosystem than m trophostega. These mature lids com- 

 pletely cover the cyclosystem. The female ampullae are very convex, 

 almost subhemispherical, slightly mieven. The free edge of the lid 

 extends in front of the ampulla like the visor of a miniature jockey cap. 

 Nematophore pits are absevt. On this specimen of pudica are lids in 

 all stages of growth, starting from small lobes on the side of cyclo- 

 system. In C. pudica the cyclosystems all tuni to the front of the 

 colony. Enlargement of figures of plate 64 is twice that of plate 63. 



A species I have provisionally identified as C. japomca (Milne 

 Edwards and Haime) (pi. 64, figs. 2-A) can be distinguished from both 

 pudica and trophostega by the size of cyclosystems and surface texture 

 of coenosteum and by the small lids, which do not contain ampullae. 

 Some cyclosystems have no Hd. In others the fid begins as a lobelike 

 outgrowth of a wider septum between two dactylotomes. The male 

 ampullae are imbedded in the coenosteum between the cyclosystems 

 and are evident superficially only as sUght irregularities of surface. 

 Diameter of cyclosystem 1.5 to 1.8 mm; dactylopores 10 to 20. Sur- 

 face of coenostemn coarsely vermiculated but not longitudinally stri- 

 ated. (Albatross station 4890, 10 to 12 miles southwest of Goto Is- 

 lands, Eastern Sea, lat. 32°26'30" N., long. 128°36'30" E., 135 

 fathoms, rocky; bottom temperature 52.3° F. Station 4924, in Col- 

 nett, or Vincennes, Strait, 30°5' N., 130°21'20" E., 159 fathoms, 

 rocky; bottom temperature 55.8° F.) 



Hickson and England (1905, p. 21) m discussing specimens of C. 

 pudica remark that "the pecuharities of this species are its robust 

 growth and the large size of the cyclosystems." Everything in nature 

 is, of course, relative. As compared to C. trophostega the cyclosystems 

 of pudica are small and its growth scarcely robust. I have inserted 

 on plate 64 (fig. 5), enlarged twice natural size as are the other figures, 

 a photograph of Cryptohelia gigantea, new species, from station 2818, 

 Galapagos Islands, lat. 00°08' S., long. 90°06' W., 392 fathoms, 

 white and black sand ; bottom temperature 43.9° F. Type, U. S. N. M. 

 no. 43273. Cyclosystems 3.5 to 5 mm in diameter, funnel-shaped, 

 with 20-25 long, shallow dactylotomes sloping evenly down to gastro- 

 stome proper. At this point the very thin ridges separating the
