-PHRYXUS HYNDMANNI. 
Female. Flattened above, ovate in outline, but slightly unsymmetrical. 
Pereiopoda equally developed on both sides of the pereion. Pleon having 
six segments, the segments being but little narrower than the hinder 
-segments of the pereion, each furnished at each side with a flattened, 
rounded-oval scale or lobe, the two attached to the posterior segment being 
rather more pointed; on the underside are two rows of elongate, conical, 
fleshy lobes, obtuse at their tips, and slightly wrinkled transversely. 
Length, about one-third of an inch. 
WE are only acquainted with a single female individual 
of this species, found attached to a Pagurus obtained at 
Groomsport, Ireland, from ten fathoms depth, by Mr. 
G. C, Hyndman, on the 24th of May, 1851, and by him 
presented to the late Mr. W. Thompson, in whose col- 
lection it is still preserved. From Phrywus Paguri it is 
at once distinguished by the rounded flat scales at the 
sides of the segments of the tail, which, indeed, appear 
rather to be but the lateral extensions of the segments
