Pachysoma Kdll, Zeit. f. wiss. Zool., 1853, IV. p. 322. Gegenbaur

 as belonging also to ^Egineta. These names were both pre- 

 occupied.

 2d Family. Brandtid^ Agass. Inscribed to the learned and eminent 

 editor of Mertens. This family is readily distinguished by 

 the peculiar lobation of the margin of the disk, but it is 

 doubtful whether it trvdy belong to this sub-order. Its quadri- 

 partite structure is indicated by the presence of four eyes.
