REVISED REPORT ON L.M.B.C. COPEPODA. 189 
Through scarceness of specimens and absence of males 
I regret the necessarily imperfect description of this very 
important addition to our fauna of a marine species of 
Cyclops, assuming as seems probable that Cyclops ewarti, 
Brady, found by Mr. T. Scott, F.L.8., about five miles 
above Queen’s Ferry, Firth of Forth, 1887, may have 
found its way thither from a fresh water source. 
Thorela brunnea, Boeck. (Pl. XVII, fig. 4.) 
Length 1.30 mm. Solitary specimens are occasionally 
taken in the open sea and in dredged material. 
Hersilioides puffim, Thompson. (Pl. XVII, fig. 5.) 
Length 0.80 mm. A few specimens were taken by tow- 
net off Puffin Island a few years ago when weekly 
gatherings of material were sent to me from there for 
examination, but it has not occurred since in the district. 
Giardella callianasse, Canu. (Pl. XVII, fig. 6.) 
Length 0.75 mm. A single specimen was taken by 
townet in Liverpool Bay during the ‘‘ Despatch”’ exped- 
ition, 1886. This species was described by M. Canu in 
‘Bulletin Scientifique’ series IIT, 1888, p. 410. 
Family NoroDELPHYIDA. 
Notodelphys allman, Thorell. (Pl. XVII, fig. 7.) 
Length 4.0 mm. A few specimens were found by Prof. 
Herdman in the branchial sacs of the Ascidian Ciona 
intestinalis dredged off the south end of the Isle of Man. 
Doropygus pulex, Thorell. (Pl. XVII, fig. 8.) 
Length 1.30mm. Found by Prof. Herdman in company 
with the preceding species, and also in the branchial sac 
of Ascidiella scabra, dredged in Groudle Bay, Isle of Man; 
also in the branchial sac of Ascidia plebera, dredged from 
the ‘“‘ Hyena,” off the Calf of Man, in twenty fathoms. 
The male (0) is smaller than the female (a).
