MADEIRA AND TTTE CANATIT ISLANDS. 



147 



the night-haul were a largely increased number of Schizopoda, 

 some of them highly phosphorescent. 



From a pretty thorough examination of the material obtained 

 at the various islands of the Canaries and Madeira, it seems 

 evident that their Copepodan fauna varies in quantity rather than 

 specifically. Eor, excepting several cases where one or two 

 specimens only of a species were found, which probably indi- 

 cated the rarity of that species, their geographical distribution 

 appeared to be general amongst the islands. 



Sixty-four species in all were obtained, as enumerated below. 

 Of these six are new to science, and three of them required new 

 genera. (See Plates X. to XIII.) 



Of the sixty-four species, twenty-two are known in British 

 waters ; and of these, thirteen belong to the family Har- 

 pacticidae. 



Following the classification given by Brady*, the sixty-four 

 species are distributed into families as follows : — 



Calanidse ... 

 Cyclopidae ... 

 Harpacticidse 

 CorycsBidae 

 Artotrogidse 



Description of the Species collected. 



Family CALANID^. 

 Calantis finmauchicus, Gunner. 

 C. VALGUS, Brady. 

 C. PEOPINQUUS, Brady. 



This species, like the two preceding, is widely distributed. A 

 high power of the microsco2ie ( x400) shows very fine hairs on 

 the inner margin of the terminal spines of the sw imming-feet, not 

 mentioned by Brady in his description of the species. 



C. TONSUs, Brady. 



C. GRACILIS, Dana. 



Both found very sparingly. 



30 species.
