Suborder ANTHURIDEA 
Only two specimens of this small suborder (only 100 species; Water- 
man and Chace, 1960) were found in the entire buoy collection, one 
from the west coast of Florida, the other from the Bahamas. They 
belong to the same family but in separate genera. The poor representa- 
tion of anthurids in the fouling samples can be attributed mainly to 
their benthic mode of life. Both were taken in scrapings from the buoy 
anchor. 
Family ANTHURIDAE 
Skuphonura species 
FIGurE 4 
Locatiry.—Florida: west coast (Station 48). 
Remarks.—The single female specimen conforms in many impor- 
tant particulars to the description of Skuphonura laticeps Barnard 
(1925a), the type and only known species of the genus. It was described 
from specimens collected at St. Thomas, St. John, St. Croix and 
Tobago, West Indies, at depths of 4 to 20 fathoms. 
The generic assignment seems fairly certain. Among the charac- 
teristics placing it in the genus are: (1) the conformity in mouthparts, 
notably maxillipeds with four free joints; (2) the complete fusion of the 
anterior five pleonic segments; (3) the pereopods with the fifth joint of 
pereopods IV-VII underriding the sixth joint; (4) the thin, subovate 
telson with paired statocysts; and (5) the nonindurated uropod with 
exopods not folding over telson. The major differences from the generic 
description are: (1) the unsutured part of the pleon is nearly as wide as 
but not wider than the pereon; (2) the sixth (free) pleonal segment is 
not narrower than the preceding segments; and (3) the flagellum of the 
second antenna is pauciarticulate, rather than uniarticulate. Since the 
genus is monotypic, it is not unreasonable to assume that some of the 
ascribed generic characteristics with which the present specimen dif- 
fers may prove to be only specific traits when additional species are 
described. The generic description may be emended accordingly. 
Among the specific characteristics of S. laticeps shown by our 
specimen are: (1) a strong, forward-directed, medioventral spine on 
the first pereonal segment; (2) pereon strongly keeled ventrally; (3) 
antennae shorter than head; (4) first pereopod with fifth joint apically 
produced and unguis narrower than finger; (5) uropod with endopod 
about twice as long as broad with apex subacute and setose, and 
exopod apically notched, crenulate, and setose. Our specimen differs, 
however, from the description of S. laticeps in the following respects: 
(1) the anterior part of the head is not expanded laterally; (2) the eyes 
hardly can be described as small with some 22 ocelli on the dorsal,
