36 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.43. 



Type-locality. — Sagami Bay, Japan. Type collected by Doctor 



Haberer. 



Genus HALISCEPTRUM Herklots. 



Pennatulidae which bear well-developed leaves devoid of spicules. 



HALISCEPTRUM GUSTAVIANUM Herklots. 



Halisceptrum gustavianum Herklots, Nederl. Tijdskr. v. Dierkunde, vol. 1, 1863, 

 p. 31. 



Colony 13.6 cm. in height; stem, to rudimentary leaves, 3.3 cm., 

 6 mm. thick with hardly any differentiated end bulb. The rudi- 

 mentary leaves are very numerous, occupying 3.2 cm. of the rachis, 

 diminishing to a mere slender band below. 



The pinnae are very numerous, closely appressed. The polyps are 

 in several rows on each leaf, very numerous, small, acorn-shaped, 

 the tentacles forming the smaller ends of the acorns. The leaves are 

 convoluted on their polypiferous borders. 



The zooids are very numerous on the ventral side of the rachis 

 on either side of a small, sharply distinguished median groove. There 

 also appear to be numerous lateral and dorsal zooids, and a dorsal 

 groove. 



The color of the colony is very light brownish, or "pallid" through- 

 out. 



LomZi^?/.— Station 4808; Cape Tsiuka, S. 61° W., 10.6 miles; 

 47 fathoms. 



Type-locality. — Amoy, China. 



HALISCEPTRUM CYSTIFERUM Nutting. 

 Halisceptrum cystiferum Nutting, Alcyonaria of the Californian Coast, 1909, p. 698. 



Colony 13.8 cm. long. Both the proximal and distal ends of the 

 specimen are missing, leaving 9 cm. of the rachis and part of the 

 stem. The number of polyps to the leaf (4 or 5), as well as their 

 size and shape, agrees well with the original description. 



The end of the stem being missing it is impossible to determine 

 whether the characteristic structure, that is, the bladder-like end bulb, 

 is present in the specimen or not. 



Locality.— St&tion 5015; lat. 46° 44' N.; long. 144° 02' F.; 510 

 fathoms. 



Type-locality. — Off Point Pinos, California, 394-609 fathoms. 



HALISCEPTRUM ALBUM, new species. 



Plate 5, figs. 2, 2a. 



There are two specimens in the collection, one consisting of the 

 proximal and the other of the distal part of colonies of this species, 

 and the following description is a composite of the two, as they 

 very nearly supplement each other.
