Specific character. Second pair of gnatliopoda having the propodos with 
the palm oblique, imperfectly defined, and slightly waved. 
Length 5 inch. 
Noenia undata. Spence Bate, Cat. Amph. Brit. Mus. p. 272, pi. xlvi. fig. 5. 
The antennae are about half the length of the animal, 
the flagellum not being longer than the last joint of the 
peduncle. First pair of legs having the hand dilated, 
slightly broader than the wrist, and tapering ; the palm 
is oblique, occupying the entire under margin, and is 
ciliated ; the finger is distinctly serrated. The second 
pair of legs have the hands ovate, and the palm oblique, 
and undulated (whence the specific name), defined by 
two or three short spines, and flanked by two or three 
short transverse rows of cilia. In other respects this 
species differs little from the last. 
It was sent to us by Mr. Alder, who dredged it on the 
coast of Northumberland.
