as the Menopon we have from the same host from Shetland. Menopon 

 gonopkaeum is quite distinct from M. mesoleuciim N. How it com- 

 pares with anatJiorax N. (C monedula) and isosternum N. (C. frugüegus) 

 we cannot say. Our Menopon from C. monedula are not of the 

 Corvine type but on C. frugüegus and C. corone a Menopon occurs 

 extremely like the species on C. corax.

The above $ apparently belongs to the species we have taken 

 on Fulmarus glacialis in Shetland. One would have been glad to 

 see the ^ also. 



Piaget (Les Pediculines, p. 499, tab. 41, fig. 1, 1880) describes 

 a M. brevifimbriatum from F. glacialis but neither text nor figure 

 applies so well to our material as does KelijOgg's account of his 

 M. numerosum from Pacific varieties of the same host. 



It is noteworthy that the European and Californian Fulmars 

 carry precisely the same DocopJiorus, Lipeurus and Ancistrona. It 

 will therefore be surprising should their Menopon parasites ultim- 

 ately prove distinct. In spite of apparently irreconciliable diiferences 

 between the descriptions quoted, we are unwilling to believe that 

 this is the case, especially as Menopon is a very generalised type. 

 It is always possible, of course, that Piaget's types were stragglers 

 on Fulmarus.
