Halitut.—Largo Bay, rare. Leucothoe is readily distinguished by the 
peculiar form of the hands of the first pair of gnathopods, which some- 
what resemble the blades of a pair of scissors with curved points. I have 
frequently taken this species, but usually in the branchial cavities of large 
Ascidians, and very seldom otherwise. I have observed it in such situations 
at Kast Loch Tarbert (Loch Fyne), at Scapa Flow, Orkney, and in the Moray 
_ Firth. It is of a delicate reddish or pink colour, and moderately active. 
It is curious that this somewhat semiparasitic habit of Z. spinicarpa has 
been so seldom referred to by authors. 
Phoxocephalus fultoni,* n.s, (Pl. XII. figs. 10-12), and Pl. XIII. figs. 
— 13-19. 
Rostrum (fig. 12) extending to about the end of the second joint of the 
peduncle of the antennules. Antennuies short, not longer than the 
peduncle of the antenne ; joints of peduncle stout, sparsely furnished with 
hairs, the last rather more than half the length of the penultimate joint ; 
flagellum shorter than the peduncle, 4-jointed joints sub-equal; secondary 
appendage 3-jointed, extending to the end of the second joint of the 
flagellum. Antenne short, stout, furnished with a few hairs, especially on 
the upper distal margin of thejoints. There is no very marked difference 
_ between the peduncle and flagellum ; second and third joints of peduncle 
about equal in length; flagellum 3-jvinted, rather longer than the last joint 
of the peduncle. The thigh of the first gnathopods is long, the anterior 
distal angle of the short stout meros is produced into a small rounded pro- 
cess; the adjacent parts of meros and wrist are correspondingly hollowed 
out, and thus a kind of ball and socket joint is formed (fig. 15, a ); hand (fig. 
15) subquadrate, the length about twice the breadth; sides nearly straight 
and parallel; palm slightly convex, and produced forward at an obtuse angle 
: from the joint of the finger; finger slightly curved, the point reaching 
_ nearly to the extremity of the palm, and fitting into a small notch. Second 
enathopods very like the first, but the hand is to some extent propor- 
~ tionally broader; the hands on both first and second gnathopods have a 
fringe of short hairs along each side of the palin. The first, second, and 
third perieopods are short and stout; the fourth are longer, the fifth are 
also short and stout. The outer branch of posterior pleiopods is 2-jointed, 
the terminal joint being very much shorter than the other; the inner branch 
a -is Ljointed, and small, being scarcely more than half the length of the 
my _ first joint of the outer branch (fig. 19). 
: , ve obtained two forms of this species; they resemble each other closely.
