In this list Rattray also includes Orlhosira occanua Briglit.,^ which is synonynKjus 

 with Aldosira oceanica (Briglit.) Lovul-Furt.^ To this I can not agree* Rattray does 

 not lak(^ note of Brightwcirs figure, whi<']i iw so unqu(^sMoniil)ly a Melosira (Orthosira 

 type) that it iw inipossibh' to classify it iu tliisgenup. It is true that Brightwell states 

 his form may be the ^^amo as Grcgory^s above-cited figure of C. concavKS. It is also 

 true that the vulval view resembles Endyciia oceanica I^lirenb. and E, minor Schmidt, 

 claspilied by Rattniy with this ppeci(\s and here admitted into the synonymy. But 

 if they all are the pamc as I^riglitwelbs form, then there is nothing to do but transfer 

 them all to the genus Melosira. Th(^ sanu; is trut; of Melodra cribrosa Breb.,'' if we 

 tak(! Brebisson's statement of its zonal view and mode of growth^ rather than that 

 observed by Smith. I have, therefore, not included this in the above synonymy, 

 though Rattray treated it as a synonym. Then^ is no (piestioii about the forms found 

 by me being roscinodiscus; nor is thtTr* any reason to doubt that the similar speci- 

 mens figured l)y Ehrc^nberg^^ and l)y ( Iregory ^ are also membtTs of this genus. Ehren- 

 berg*s example is unfortunately nbnormnl; but that it stands for Ids C. eoncavuSy 

 rather than the (juite different f{jrm previously figured,/ is proved by the fact that in 

 his summary of his genera and species he refers to his figure in plate 21, but excludes 

 that in ])late 18. It may be added (hat the difliculty here brought out of placing 

 tlic above Endictya forms with this species gives emphasis to the doubt expressed 

 by me in discussing the present genus as to the union of Endictya with Coscinodiscus. 



Found at station 2807, Galapagos Islands.
