64 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.43. 



The operculum is strongly developed, conical, each flap consisting 

 of a triangular scale beset with sharp points, the inner scales not 

 much smaller than the outer. 



Locality. — Station 4784; East Cape, Attu Island, S. 18° W., 4 

 miles; 135 fathoms. 



General distribution. — The type-locality is Japan. 



The specimen differs from the type in the superficial granulation of 

 the scales and the presence of spines on many of the marginal scales, 

 but it agrees well in other details. 



PLUMARELLA CARINATA Kinoshita. 

 Plumarella carinata Kinoshita, Primnoidse von Japan, 1908, p. 17. 



Several specimens, mostly fragmentary, evidently belong to this 

 very well-marked species. 



The calyx scales differ from others of the genus, except P. costata 

 Ktikenthal, by having well marked median carinas. These keels, 

 however, are not easily seen when the specimen is immersed in fluid ; 

 but become quite evident when the specimen is partly dried. 



Another characteristic pointed out by Kinoshita is the compara- 

 tively small size of the abaxial scales, these being actually smaller 

 than the laterals, a character that is very rare in this family. Another 

 peculiar feature is the abrupt turning upward of the calyx, which has 

 its basal part projecting outward and its distal part turned upward, 

 thus resembling a tobacco pipe in form. This results in the adcauline 

 side of the calyces being entirely free from the branches. 



Localities. -^tsition 4893; Ose Saki Light, N. 29° E., 5.5 miles; 106- 

 95 fathoms. Station 4894; Ose Saki Light, N. 41° E., 5 miles; 95 

 fathoms. Station 4895; Ose Saki Light, N. 42° E., 4.7 miles; 95 

 fathoms. 



General distribution. — The type-locality is Kozu Island, south of 

 the Province of Izu, Japan. 



This species very closely resembles Plumarella cristata Ktikenthal,* 

 with which it may be identical, although this is denied by Kinoshita. 



PLUMARELLA SPICATA. new species. 

 Plate 8, figs. 2, 2a; plate 18, fig. 6. 



A number of fragments from Station 4780 resemble Plumarella 

 longis'pina Kinoshita,^ but seem to be fairly distinct. 



Colony very loose and straggling in habit, flabeUate, irregularly 

 branching. The terminal twigs are about 6 to 8 in 5 cm. in length of 

 branch. The calyces are irregularly distributed on two sides of the 

 branch, and are only accidentally in pairs. They often project at a
