378 cnUSTACEA OF NORTHUMBERLAND AND DURHAM 



One of the commonest of the Harpacticidae, occurring 

 abundantly between tidemarks, and less profusely in greater 

 depths of water down to at least 40 fathoms. N.D. 



Dactylopusia neglecta G. O, Sars. 



1880. Dactylopiis tislnn'dcs, Brady (3) (brackish water 



variety), vol. ii., p. 108, pi. liv., figs. 14-16. . 

 1905. Dactylopusia neglecta, G. O. Sars (6), vol. v., p. 127, 

 pi. Ixxviii., fig. 2. 

 This was briefly noticed and figured in the " Monograph of 

 British Copepoda " as a brackish water variety of D. tislwides, 

 but the characters are distinctive enough to have warranted 

 Professor G. O Sars in giving it specific rank. The only 

 local record is "brackish pools at Seaton Sluice, Northumber- 

 land" (G. S. B.) N. 



Dactylopusia brevicornis (Glaus). 



1880. Dactylopus brevicornts, Brady (3), vol. ii., p. 118, 



pi. Ivii., figs. 10-12, pi. Iviii., fig. 14. 

 1905. Dactylopusia brevicornis, G. O. Sars (6), vol. v., 

 p. 130, pi. Ixxx. 

 Not uncommon on the fronds of Laniinaria saccharina at 

 Sunderland (G. S. B.) D. 



Dactylopusia platycheles (G. S. Brady).

 East Coast of England. Nat. Hist. Trans. Northum-

figs. 4-6. 



1899. Dactylopus longirostris, Brady, On Ilyopsyllus 



coriaceus and other Crustacea taken at Alnmouth. 



Nat. Hist. Trans. Northumberland and Durham,
