The "genus" Peneus (type P. monodon) was established in the year 1798 

 by Fabricius for three species from the " Indian Ocean." One of these species 

 P. planicornis, is described as having the antennular fiagella compressed, and so 

 should, perhaps, be transferred to the genus Solenocera of Lucas. 



H, Milne Edvrards recognised eleven species of Peneus, but two of them 

 have since been transferred to Solenocera. 



In 1881, in a preliminary notice of the " Challenger " Peneidea^ based 

 upon a critical examination of the elder Milne Edwards' typical specimens, 

 Spence Bate enumerated sixteen species under the genus Peneus, exclusive of 

 one of Milne Edwards' species which he wrongly transferred to Peneopsis. 

 [Peneoj)sis A. M. Bdw., has never, I believe, been characterized formally ; l)ut 

 as, like Ealijwrus and all Peneinas except Peneus, it has a pair of arthrobranchiae 

 on the penultimate pair of legs, it need not be considered further in this place].
