286 TESTACELLID^ 



[Knapp {Journal of a Naturaliftf, 1829, p. 341) records 

 the occurrence of " Testacellus halotideus " [sic], by 

 which from the context he probably intended the 

 present species, though he obviously was not aware 

 there was more than one.] 



First definitely recorded from Guernsey in 1834, by 

 F. C. Lukis (Mag. Nat. Hist., vii, p. 224), and from 

 the British Zoological area in 1852, by Forbes & 

 Hanley. {See ref. above.)
