CoROPHIIDA. 
Siphonoecetes collettt, Boeck. 
This species was obtained in a gathering collected about fifty miles 
south-south-east of Fair Island on October 16th, 1900. ‘Sritish speci- 
mens of this species have sometimes been recorded as Stphonoecetes typicus, 
Kroyer ; but it seems that Kroyer’s S. typicus is a truly Arctic species. 
Corophium grossipes (L.). 
A few specimens of this Corophiwm occurred in a surface tow-net 
gathering collected by the “Garland” off the Ferry Slip at Invergordon, 
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 Corophiwm may irequently 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 coutinuously 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. 
Corophium 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.* 
DULICHIIDA. 
Letmatophilus tuberculatus, 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, ou October 19th, 
1900. Letmatophilus 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 specithen obtained 
off Fair Island might belong to the same species, but a careful examination 
showed that it was the Lematophilus 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. Latmatophilus
