718 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. xxxv. 



The polyps are distributed on all sides of the stem and branches, 

 but with a strong tendency to a bilateral arrangement, especially on 

 the ultimate branchlets where they are arranged as in typical species 

 of Leptogorgia. Polyps with a distinct colleret. 



The calyces are short truncated cones usually less than 1 mm. 

 high and 2 mm. broad at base, about 1.5 mm. apart and directed at 

 a right angle from the stem. 



The spicules are slender, often curved, pointed spindles covered 

 with scattered spinules and nodules. There are a few short stout 

 forms. The spicules of the colleret are conspicuous curved spindles. 

 At the base of each tentacle a few spicules are arranged in chevrons, 

 and beyond these the tentacular spicules are longitudinally disposed 

 in two or more rows. In the calycular walls the general arrangement 

 of spicules is longitudinal, although many are transverse or oblique, 

 as they are on stem and branches. 



The color of the colony is reddish brown, the spicules having a 

 slight reddish tinge. 



Distribution. — Station 4461, Point Loma light-house S. 3° E. 9.3 

 miles, 285 fathoms. 



The type was secured by the Challenger at Station 232, off Japan, 

 345 fathoms. 



The specimens taken by the Fisheries steamer Albatross differ 

 slightly from the type, particularly in having a well-marked colleret 

 and in the arrangement of the calycular spicules. 



Genus EUMURICEA. 



Colony branched; calyces verruciform or tubular, showing an 

 8-rayed figure in retraction. Spicules in the form of sharp pointed 

 needles. 



EUMURICEA PUSILLA, new species. 



Plate LXXXVIII, figs. 3 and 4. 



Colony branching in an irregular manner, a little over 37 mm. in 

 height. The main stem gives forth roughly alternate branches at 

 irregular intervals, the two longest being 13 mm. apart, the whole 

 colony being roughly flabellate. 



The calyces are on opposite sides of the stem and branches, alter- 

 nate, 2.5 mm. from summit to summit, forming low rounded domes 

 or cones, 8-rayed on the summits, about 1 mm. high by 2 mm. broad. 



The calycular walls are covered with very hispid spicules, which 

 have their edges somewhat overlapping and are, in general, disposed 

 transversely rather than otherwise. 



The polyps are completely retracted in the specimen secured. Dis- 

 section shows that they have the colleret characteristic of this family. 

 The tentacles are heavily armed with large jagged spindle-shaped
