dei'ived as a wliole from tho west and soiitli. and not from the east or nortli. In its 

 entire faeies, tlie fauna is strikini>ly unlike tiiat of the Pacitic coast of Mexico and 

 Central America, and resembles strong-ly the assemblag-e of forms discovered l)\' the 

 Alhaf.t'oss and the Cludlerujer oli' tlie coasts of Japan and the Elast Indies. Some of 

 its members tind their nearest known affines in tlie 15ay of Bengal. In addition to 

 the ich^ntical species already mentioned as occurring in Japan or the East Indies, the 

 list includes species of the following genera: Promyllanto)\ PoJy'ipnm^ Macrorhain- 

 phoKtiK, fcldln/oeanqjus, PegaxuK, J'oh/miriii., Autigonia^ Stet/wj>r).stes, Cyttouiuiius^ 

 A't'acan(u Txiuduotwi^ B^iiiJiriidiinii, llopliehthyx, Bevihrops^ Chrionema, Ptei'opm- 

 ron., Chmiipnochn, DraciDicttd, Atcleojim, Pa'cilopsi'ifa, Tx/viopsc'ttn, Snmar/'setts. 

 Aiitieifharun, Ohasatnopxctta, and Chatoia.j; all of which have close relatives in 

 Japan, the South Seas, or the Bay of Bengal, ))ut are quite unrepresented along 

 the eastern shores of the Pacilic. Even the more characteristically bathybial forms, 

 such as the macrurids, indicate a similar relation, as is shown by the presence of 

 (radomii--:, Melanohmnchns, Optonurm, TTyinimoeephidus^ Malacocephalns, and Tni- 

 c.lwmirm. Among the above-named genera, Pohjmi.eia, Ant'igonin. Gadomus^ Md- 

 midhrauehus^ I[yiiienoe<p>]i(diiK, and MaJucovepludux have close representatives in the 

 eastern Atlantic as well as in the western Pacitic, a fact of some interest when con- 

 sidered in connection with the known distribution of many shore forms of Japan and 

 the South Seas, whi<-h are unrepresented along the Pacific coast of America, but art- 

 present either as identical or as closely i-clalcd s[>ccies in tlie iMcditei'i-aiicaii and 

 neighboring waters. 



In this paper are included all the Kshes obtained with the dredge, trawl, or tan- 

 gles, and idso the scopelids among those taken at the surface. Other pelagi<- forms 

 from the surface ai'e reserved for a subsetiuent paper.
