113 Part III. — Twenty-third Annual Report 



but merging into blackish brown along the middle and towards the 

 proximal end ; the elytraform plates and thoracic feet, which also appear 

 to be chitinous, are whitish with a slight tinge of yellow. 



I am indebted to Mr. Irvine for the opportunity of examining and 

 describing this interesting species. 



Drs. Steenstrup and Liitken in the work referred to above give a 

 series of excellent figures illustrative of the structure of the male of 

 Anthosoma, and it would appear from the description and figures of these 

 authors that the large foliaceous and elytraform dorsal plates which cover 

 the posterior part of the female are absent in the male.

The Rev. Canon A. M. Norman, to whom I am often indebted for 

 information and help in Natural History research, has, with his usual 

 kindness, permitted me to examine a specimen of this curious copepod 

 parasite which he received many years ago from the late Thomas 

 Edward of Banff, who found it on a short sunfish, Orthagoriscus mola, in 

 the Moray Firth. The species is recorded in Smiles' Life of Edward, 

 among the many other Natural History rarities mentioned at the end of 

 that work, under the name of Pennella fibrosa. Linnaeus in his 12th 

 Edition of Systema Naturae, referring to the host of Pennella filosa, says, 

 " Habitat in M. Mediterranei Xiphiis."

A Lemma apparently belonging to this species was found adhering to 

 a small Gadus luscus sent to the Laboratory from the fish market at 

 Aberdeen on January 12, 1905. The various species belonging to the 

 genus Lemma fix themselves to the gills or gill-arches of the fishes 

 infested by them, but the specimen now recorded had its head buried 

 in the flesh of the fish some distance behind the operculum, as shown in 

 the drawing (fig. 18). This is the first example of the kind I have met 

 with.
