lateral, and ventral sides of the head; and (3) the palm of the first 
pereopod bears a low, blunt tooth. 
Since the description of this species is based primarily on the male 
and the only specimen is a female, the character of the second pleopod 
can not be compared; moreover, it may be that some of the above- 
mentioned differences (both specific and generic) may be due merely 
to sexual dimorphism. Barnard (1925a), for instance, indicates that 
the head is less expanded in the young, which one also might assume 
to be the case in females. 
The alternatives implicit in the foregoing discussion are (1) to 
identify the lone specimen as the female of Skuphonura laticeps 
Barnard, (2) to describe it as a new species of Skuphonura with an 
emended diagnosis of the genus, or (3) to identify it only to genus. 
The first alternative would result in a considerable extension of geo- 
graphic range of S. latuceps, which is ecologically plausible since both 
occur in warm waters. The second possibility does not seem feasible 
at this time with the material available; it easily could result in an 
addition to synonymy. The third possibility seems to be the best 
decision in this case, leaving the opportunity open for action on the 
other two when more material is at hand. 
Accalathura species 
FIGURE 4 
Locauity.—Bahamas: Walker Cay (Station 59). 
Remarks.—The second of two anthurid species in the buoy collec- 
tions is represented by a small (3.5 mm) immature specimen that is 
assigned tentatively to the genus Accalathura Barnard (1925a). Its 
immaturity is indicated by its small size and the presumably incom- 
plete development of the seventh pair of pereopods, which are about 
half the length of the sixth pair. This makes its determination uncer- 
tain and incomplete. 
The generic assignment is based on the following characteristics: an 
unpaired statocyst at the base of the telson; a relatively short, dis- 
tinctly segmented pleon; the fifth joint of the posterior pereopods not 
underriding the sixth; and a 4-jointed maxilliped. There are several 
discrepancies, however, between the generic description and the speci- 
men, probably associated with its immaturity; for instance, the flagella 
of the first and second antennae are uniarticulate and pauciarticulate, 
respectively, rather than both being multiarticulate. 
It has not been possible to identify our specimen with either of the 
two species of Accalathura known to occur in the Antillean region, 
namely, A. crenulata (Richardson) and A. crassa Barnard. Accalathura 
crenulata has been reported from the Bahamas and other tropical 
Atlantic localities (Yucatan, Brazil, Danish West Indies, and Cape 
Verdes) at depths of 5 to 40 fathoms (9-72 meters); A. crassa is
