ANONYX HOLBOLLI. 
107 
appendages has its branches subequal ; the penultimate 
pair are shorter than the preceding, or ultimate pairs. 
The terminal central piece is deeply divided, and each 
division has its apex truncated, and furnished with a 
central spine. 
The colour of the animal is transparently white, hav- 
ing spots of rose-colour near the dorsal surface, on each 
each side of the body, which in some specimens are less 
distinguishable in outline, their place being only indi- 
cated by a blush of the same colour. 
The original specimen was taken at Sukker-topper, by 
M. Holboll, in compliment to whom Kroyer proposed 
the specific name adopted above. We have received 
specimens from our valued correspondent, the Rev. Geo. 
Gordon, of Elgin ; also from our indefatigable friend, 
Mr. Edward, of Banff ; and Mr. Barlee has dredged it 
on the Haaf, about thirty miles off the Shetlands. It 
has been taken by the Rev. A. M. Norman and Mr. J. 
Gwyn Jeffreys in the outer Skerries Harbour, Shetland. 
Mr. Loughrin has sent us a half-grown specimen from 
Polperro, on the coast of Cornwall, and we have dredged 
it in Plymouth Sound.
