202 THE SCHIZOPODA. 
Remarks.— Illig states (Zool. Anz., 30, 1906, p. 202) that the endopod of 
first pair of thoracic legs is wanting in #. fowleri and in his two new species 
of Euchaetomera, among which is the above-named E. limbata. As to E. tenuis 
Sars = FE. fowleri Holt and Tatt. his statement is incorrect; the endopod is 
well developed both in the maxillipeds, the gnathopods, and in all six pairs of 
real legs; I am inclined to think that the same is the case in his two other species. 
Distribution.— Sars’s type was captured in the South Pacific off the coast 
of Chile. The ‘‘Siboga” secured it at two places in the Indian Archipelago. 
According to several authors (Ortmann, Tattersall, Holt and Tattersall, and 
myself) the species is widely distributed in the tropical and northern temperate 
Atlantic, in its eastern part going northwards to West of Ireland; and it has 
been taken in the Western Mediterranean also.

Plate 3, figs. la-lb. 
Sta. 4583. Oct. 11, 1904. Lat. 22° 45’ N., long. 110° 5’ W. 300 fms. to surface. 1 immature speci- 
men. 
Sta. 4676. Dec. 5, 1904. Lat. 14° 28.9’ S., long. 81° 24’ W. 300 fms. to surface. 1 male, (Type), 
perhaps not quite adult. 
Description.— Allied to EF. tenuis G. O. S. and #. oculata H. J. H.— The 
frontal plate (fig. la) shaped as a low, broad triangle with the two sides a little 
coneave and the vertex moderately broadly rounded.— The eyes about as thick 
as in E. tenuis, but the posterior area with acting facets is much larger, being 
longer than broad and the distance between the anterior and the posterior 
area at the outer margin distinctly less than half as long as the outer margin 
of the posterior area, while in ZH. tenuis that distance is about as long as the 
whole outer margin of the posterior area which is shorter than broad.— The 
antennal squama is five times as long as broad, with the outer margin almost 
or quite straight, no external tooth and the terminal lobe beyond the most — 
proximal outer seta a little longer than broad.— The rami of the uropods (fig. 
1b) broader in proportion to length than in Z. tenwis.— Telson somewhat broader 
than long, otherwise as in L. tenwis. 
Length of the male 5 mm., but the specimen is perhaps not quite full grown. ; 
Remarks.— E. plebeja is instantly separated from FZ. tenuis by the much |

longer posterior dark area of the eyes and by the at least nearly straight outer 
margin of the antennal squama. J. oculata differs from E. plebeja by having 
a very conspicuous, somewhat narrow frontal plate, by considerably thicker 
eyes and by having the antennal squama only three and a half times as long 
as broad.
