422 KUCRANTA VILLOSA. 
Habitat—A single example of Chrysopetalum debile, of the Family Palmyridee, was 
dredged on a bottom of sand and shells in Clew Bay (Southern). 
Distribution.—Villafranca, Mediterranean (Grube) ; Madeira (Langerhans) ; ? California 
(Johnson). 
The occurrence of a representative of a genus, characteristic of the warmer seas, on the 
West Coast of Ireland, indicates the richness of this remarkable region, and the possibility 
of further interesting discoveries yet in store for the Marine zoologist. In the description 
of Palmyra aurifera, Savigny, in the ‘“‘ Challenger” Annelids Chrysopetalum debile is alluded 
to in connection with the presence of scales.t 
Famity PoLtyNnor”. 
Genus HucRANTA, Malmgren, 1865. 
Lateral tentacles springing from each side of the base of the median, the three occupying 
the whole breadth of the region. Palpi subulate, minutely papillose. Fifteen pairs of elytra, 
covering the dorsum with the exception of the ultimate segments, and occupying the feet— 
1,3,4,6,8 . . . . 22, 25, 28,31. Dorsal bristles forming a dense tuft which scarcely 
reaches the bases of the ventral bristles, each of the internal bristles somewhat curved at 
the tip, and furnished with rows of spikes. Ventral bristles longer, in horizontal groups, 
the upper series longer and bifid (the secondary process being unusually long), all with rows 
of spikes.
