(Geno- type, Pseudoplesiops typus Bleaker.) Nematochroniis Webek, Sifeogfa-Expeditie, vol. 57, Fische, p. 264, 1913. (Geno- type, Nematochromis antme Weber). The species referable to the genus Pseudoplesiops need much clari- fication, but they seem sufficiently similar in regard to certain char- acters to indicate that the five species, typus Bleeker, annae (Weber), Tosae Schultz, and the two new ones, revellei and sargenti, belong to- gether. This is done on the basis of an absence of spines in the median fins, with the first several rays of the dorsal and anal fins simple or unbranched; the reduced number of soft rays in the pelvics (1,4 or. Figure 65.—Holotype of Pseudoplesiops rosae Schultz ( No. 116178), from Rose Island, Samoan group. (Drawing by Aime M. Awl.) 1,3) and their great elongation (reaching past the anus or anal origin); the usual occurrence of cycloid scales, although a few speci- mens may have ctenii along the upper part of the back; a ring or series of pores around the edge of the orbit, with an enlarged pore in the interorbital space; and three or four rows of scales on the cheeks. The presence or absence of lateral lines is variable and the reduced denti- tion on the palatines, in which teeth may be present in certain species and absent in others, suggests characters of less significance generi- cally. Other characters common to this genus are the few short gill rakers; similarity of dentition on jaws; gill membranes that extend far forward, where they join each other and form a narrow fold across the isthmus.
