GLOSSOBIUS A SYNONYM OF CERATOTHOA Oues 
Olencira, Leach, 1818, has but one species, but that the 
remarkable Olencira preequstator (Latrobe) of America, in 
which the first six pairs of feet from before backwards are 
successively and gradually longer, but the seventh pair 
abruptly much so. 
Ajgathoa, Dana, 1852, is not mentioned by Schiddte and 
Meinert. The definition, Mr. Harger says, is :-—‘ Body 
elongate oval; pleon not suddenly narrower than the 
thorax ; head large, subtriangular; eyes large; legs nearly 
alike throughout, with strong curved dactyli; epimera of 
moderate size or small; pleon long and large, composed of 
six distinct segments ; pleopoda not ciliated ; uropods more 
or less distinctly ciliated, rami subequal.’ Mr. Harger 
remarks that the large granulated eyes remind one of Avga, 
and that the ciliated uropods aiso indicate the approxima- 
tion of this genus to the preceding family. The ciliation 
is, however, nearly rudimentary in the New England species, 
Afgathia loliginea, Harger. 7 
Lobothirax, Bleeker, 1857, is distinguished by the 
strong dorsal carination along the first four segments of 
the perzeon, and the deep sinuation in the centre of their 
hinder margin. ‘The species are Lobothorax typus, Bleeker, 
from Batavia, and Lobothorax auritus, (Schiddte and 
Meinert) from the Philippines. From what must be con- 
sidered a fanciful objection to the formation of the name 
Lobothorax, the latter authors thought proper to change it 
into Saophra, which they made the leading genus of their 
family Saophride. 
[ Glossobius |, Schiddte and Meinert, 1885, is notable for 
the great disparity in size between the male and female. 
Of Glossobius linearis (Dana) the two often quoted authors 
give five descriptions relating to the adult male and female 
and to three stages of the young. ‘The ovigerous female 
attains a length of an inch and a half, while the adult male is 
content with about two-fifths of an inch at the largest. The 
generic name signifies ‘tongue-life,’ and the species men- 
tioned infests several kinds of flying-fish in a way that jus- 
tifies the name. ‘'The female embraces the fish’s tongue, 
perforating its lower conjunctive membrane with the very
