On British Land Ifiopoda. 369 



time when I was employing that old coastguarclsman to collect 

 fish-parasites for me. He said that he had found it on the 

 blue shark at Polperro. 



The two Cornish specimens agree in every particular with 

 Milne-Edwards's description and capital figures (Hist, des 

 Crust, vol. iii. p. 472, pi. xxxviii. figs. 13, 14). I am not 

 aware that the species has been recorded by any other author ; 

 and the type specimen was from near Tongatubu, Friendly 

 Islands ! 



CONGERICOLA, J. van Beneden. 



This name must be used with van Beneden's type G. pal- 

 Uda. The earlier name Ci/cnus, H. Milne-Edwards, 1840, 

 had been preoccupied by Hiibner, 1816, for a genus of 

 Lepidoptera. 



CiREIPEDIA. 



Genus Tkypetesa *, nov. nom. 



Type Tryrpetesa (Alcippe) lanipas (A. Hancock). 



Unfortunately the name Alcippe, which Hancock gave to 

 tliis very interesting burrowing Lepas found off the North- 

 umberland coast by him, was preoccupied by Blyth in 1844, 

 and is in use for a genus of birds. The genus Alcippe, 

 Hancock, is not to be found in either Scudder or Waterhouse 

 and Sharp. In Scudder, moreover, Alcippe, Blyth, did not 

 appear ; and it was no doubt in consequence of this that a 

 third genus Alcippe was instituted in 1896 among insects. 



XLVIII. — British Land Lsopoda. — Supplement. 

 By Canon A. M. NoRMAN, F.R.S. &c. 



In the '■ Annals ' for January 1899 (ser. 7, vol. iii. p. 70) I 

 published a paper containing notes on all the Land lsopoda 

 known to belong to our fauna up to tliat date. Three species 

 have since been added, which I will now notice, with some 

 other brief remarks. 



Genus TiUCHONlSCUS, Brandt. 



Trichoniscus vividus (Koch). 



Dr. Scharff has recorded this species from Cappagh, Co. 



* TpvTrr]TT]s, a borer. I have used this particular ending- because Tri/- 

 petes and Trypeta are already in use.
