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.
