So little is known concerning the structure and affinities of Alpheus pdagi- 

 cus Eisso,* the type species of the genus Miersia Kings!. (= Uphp-a Eoux, 

 mm. prceoc), that it seems best to ignore Iliersia {Ephum) as based upon a 

 species at present indeterminable, and to suppress family and subfamily 

 names derived therefrom. The lower Atyidm, genera characterized by palp- 

 less mandibles and by the presence of exopods on all the thoracic leo-s t 

 may receive the subfamily name Paratvinw, from Paratmi Mior,^

 from the Paratyinm to the Alyinw, Ephyra hwcketii v. Mart.** belongs to the 

 family IIophpJioridcB and probably to Acanihephyra, subgcn. SystcUaspis Bate.

 Ephjrinoi by Ortmann (Zoolog. Jabrb., Abth. f. Syst., V. 456, 1890).

 Part L, type, Atyaephyra rosiana Brito Capello. Ortmann (Zoolog- Jahrb., Abih. f. Syst., V. 464, 1890) 

 has recently cstabUshed the gcaus Jlemicaridina for the reception of Ilippolyte desmaresHi Millet {Cari- 

 dma desmarestii Joly). Since this species is strictly congeneric with Aiycphyra rodana, Ilemicaridlna be- 

 comes a synonynic of Aiyephyra.
