REVISED REPORT ON L.M.B.C. COPEPODA. 199 
as broad and have each a strong curved claw extending 
dorsally situated rather above the centre, two strong 
spinous sete adorning the opposite side. The caudal 
segment is terminated by a strong central spine, and on 
the inner side has a stout bluntly rounded spine about 
half the length of the caudal segment, and a short fine 
seta on the outer side. 
Two specimens, male and female of this strongly marked 
Copepod were lately dredged at a depth of seven fathoms 
on the muddy ground inside Port Erin breakwater. In 
the general character of the antenne this species somewhat 
resembles L. serrata for which it might at first sight be 
mistaken, but the swimming feet are different, and the 
caudal segments and their remarkable appendages clearly 
distinguish it from any known species. 
Laophonte thoracica, Boeck. (Pl. XXI, fig. 5. e.—g.) 
Length 0.60 mm. Our only specimen was taken by 
townet amongst the Algz round Puffin Island. 
Laophonte horrida, Norman. (Pl. XX, fig. 7.) | 
Length 1.25 mm. This ferocious looking animal is at 
once recognisable by its array of dorsal projecting spines. 
A few specimens male and female were recently dredged 
at four fathoms in Port Erin Bay and one specimen was 
dredged at 39 fathoms, 12 miles from Port Erin. They 
were imbedded in mud which was so tenaciously held by 
the spines that it was most diffcult to clean them. It 
appears to be an exceedingly rare species. 
Laophonte similis, Claus. (Pl. XXI, fig. 5. a.—d.) 
Length 1 mm. Found in tidal pools about the sub- 
marine forest at Leasowe, also in dredged material from 
Colwyn Bay. 
Laophonte curticauda, Boeck. (Pl. XXI, fig. 3.) 
Length 1mm. Found in tidal pools at Hilbre Island, 
Leasowe, and Puffin Island.
