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 Phryxus 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
