is, though Bhowing marked similarity to l>"th Anaulus Ehrenb. and Por- 

 I ill. and, therefore, more remotely to Biddulphia < rray, is clearly distinct. 1 1> 

 identity with the 1 1 1 r« •• - genera enumerated in the synonymy is generally recognized, 

 though I'-- Toni and a few others preserve the separate rank "i' Pleurodeamium and 

 Bydrosera. In regard t<» the former it is sufficient to note that the only striking di ffer- 

 ence is its finer beading of the middle band zonal \ iew and coarser beading of the 

 Lateral bands, and we find in T. intermedia Grun., an otherwise typical T. mueica, the 

 beadii odesmium brebissonii Kin/., so that, as Grunowaays, the two genera 



rtainly the same. The genus Tetragramma was made on Buch insufficient dis- 

 tinctions that Bailey himself afterwards abandoned it.6 Bydrosera even in its usual 

 triangular form Bhows the music notes and all the characteristics of Terpsinoe.
