NOTES ON JAPANESE SCHHOPODA. 



253 



uropod about one and a half times as long as telson, much dilated at 

 base ; spines on the ventral side quite invisible. Average length of 

 body 7.3 mm. 



Localities. Misaki in Prov. Saganii ; Enoura in Prov. Suruga ; 



Tateyama in Prov. Awa. In all these localities the species is taken 

 in great quantities by fishermen. 



Notes. — Tliis species can be easily distinguished from others of the genus by the armature 

 of the mandibular palp and by the characteristic features of telson. In other points the 

 species closely resembles À. laticauda Hansen. 



7. Anisomysis mixta n. sp. 

 Plate VIII., figs. 28, 34. 



Diagnosis. Carapace with distinct rostrum. Third joint of 



antennular peduncle nearly equal in length to basal joint. The three 

 pairs of flagella markedly different in length according to sex ; more 

 than twice longer in male than in female. Eye large, somewhat 

 reniform. Antennal peduncle half as long as the scale. Propodite in 

 posterior six pairs of legs shorter than carapace, composed of two 

 joints. Fourth pleopod of male (fig. 28) reaching down to end of telson ; 

 the last joint of its outer branch more than twice as long as the 

 middle joint. Telson (fig. 34) about one-third as long as the last 

 abdominal segment, triangular in shape ; its posterior half fringed with 

 about 24 spines which increase in size posteriorly. Uropod as in A. 

 ijimai. Average length of body 5. mm. 



Locality. Misaki in Prov. Sagami. 



Notes. — The characteristic features of this species consist in the jointed structure of the 

 fourth pleopod in male and in the triangular shape of telson. TI12 species is of a smaller 

 size than A. ijimai, with which it occurs together but always in a less number.
