time when I was employing that old coastguardsman 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- 

 lida. The earlier name GycnuSj H. Milne-Edwards, 1840, 

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

 Lepidoptera.

Genus Trypetesa *, nov. nom. 



Type Trypetesa (^Alcippe) lampas (A. Hancock). 



Unfortunately the name Alcippe, which Hancock gave to 

 this 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. Tlie 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. 



* TpvTrrjTTjs, a borer. I have used this particular ending because Try- 

 petes and TryiJeta are already in use.
