266 Part III. — Nineteenth Annual Report 



Corophiid^. 



Siphonoecetes colletti, Boeck. 



This species was obtained in a gathering collected about fifty miles 

 south south-east of Fair Island on October 16th, 1900. British speci- 

 mens of this species have sometimes been recorded as Sijphonoeeetes typicus, 

 Kroyer ; but it seems that Kroyer's S. typicus is a truly Arctic species. 



Gorophium grossipes (L.). 



A few specimens of this Gorophium occurred in a surface tow-net 

 gathering collected by the " Garland " off the Ferry Slip at Tnvergordon, 

 Cromarty Firth, on June 16th, 1900. The usual habitat of this species 

 is in brackish-water pools which have a soft muddy bottom, and it occurs 

 in pools of this description at the mouth of the River Alness, a few miles 

 to the west of Invergordon; these pools are occasionally covered by the 

 sea at high water. In such pools the Gorophium may frequently be 

 observed rising quickly out of the mud, and after swimming a short 

 distance drop down and as quickly disappear, being apparently unable to 

 swim continuously for any lengthened period. The presence of the speci- 

 mens in the surface tow-net, therefore, may probably be due to their 

 having been carried down by the ebbing tide while clinging to some float- 

 ing rubbish ; that this explanation of their presence in the surface tow- net 

 is probably the correct one is borne out by the fact that several beetles 

 and other insects were also observed in the same gathering. 



Gorophium affine, Bruzelius. 



Though I only record this species for the Moray Firth now, the one or 

 two specimens obtained were dredged in 1895 on July 25th. The 

 material in which they were obtained was dredged from 100 fathoms a 

 few miles to the northward of Rosehearty. The marked difference in the 

 form of the third pair of uropods, together with the slender antennules, 

 makes this species easily distinguished from the other members of the 

 genus. 



Unciola planipes, Norman. 



This species was dredged by the "Garland " off Aberdeen in 45 fathoms, 

 November 7th, 1900. Unciola planipes was described from specimens 

 which Dr. Norman dredged in deep water off the Northumberland coast.* 



DulichiidjE. 



La3tmatophilus tuberculatus i Bruzelius. 



This rare species was represented by a damaged specimen in a gather- 

 ing collected by the steam trawler " St. Andrew " about fifty miles 

 south-east of Fair Island, in about 60 to 65 fathoms, on October 19 th, 

 1900. Lcetmatophilus armatus (Norm.) was obtained by Rev. A. M. Nor- 

 man in material dredged from 100 to 110 fathoms, N. by W. of Burra- 

 firth Lighthouse in 1867, and I at first thought that the specimen obtained 

 off Fair Island might belong to the same species, but a careful examination 

 showed that it was the Laimatophilus tuberculatus of Bruzelius. G. O. 

 Sars describes this species as rather abundant in several localities off the 

 west coast of Norway in depths of 20 to 50 fathoms. Lwtmatophilus
