 to that species being really a closely allied one which has been 

 provided by Professor G. O. Sars with a new name — Z. scotti. 

 Tetragoniceps bradyi and Laophonte denticulata are interesting

 are described on the strength of single male specimens only, 

 but are nevertheless, as I think, quite sufficiently characterised. 

 The genus Oncaea has not previously been met with, as I 

 believe, in the British area, though many species from more
