"GATS: loa 
outer branch bearing on its external margin, near the 
apex, three marked spines (fig. 8), each of which is 
bordered externally with a closely appressed series of 
radiating filaments, each group having much the appear- 
ance of a minute hair-brush. Outer branch of the fifth 
pair of feet in the female (fig. 9) elongated, quadrate, 
bearing five terminal sete, and closely ciliated on the 
outer margin; inner branch short and broad, densely 
ciliated, and bearing two long and two or three short 
hairs: in the male, the inner segment is obsolete, the 
outer not much differentfrom that of the female. Caudal 
seoments short and broad; inner tail-setz stout, about 
as long as the abdomen, outer scarcely half as long. 
Colour pale yellowish, the central body-segments some- 
times tinged with lilacor blue. Length 7th of an 
inch (‘52 mm.). 
This species does not seem to be of very frequent 
occurrence, but is perhaps commoner on the east coast 
than elsewhere. It was first found by Mr. Goodsir in 
the Firth of Forth, and I have taken it in several places 
on the coasts of Durham and Northumberland, usually 
amongst Laminaria saccharina or other Fuci. Dredged 
in 10—12 fathoms amongst the Scilly Islands, and in 
Ventry Bay on seaweeds. Mr. Norman has found 
it amongst weeds in Balta Sound, Shetland, and 
between tide-marks at Oban.
