338 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.xxiii. 



numerous acute spines scattered along- its dorsal surface; 2 spines 

 between dorsals. Patches of sharp, fang-like, depressible spines near 

 the edges of the disk opposite the eves, and also near the angles of 

 the pectorals; the latter in 2 rows. Small prickles on upper and 

 lower sides of snout near its tip, and along edges of disk anterior to 

 the lateral angles. Other parts of bod}' above and below naked. 

 Color in spirits, Ijrownish with many punctulations not larger than 

 pupil, scattered over entire upper surface except edges of tins and the 

 quadrangular spaces between the anterior pectoral rays and the rostral 

 cartilage; the latter region is yellowish white, similar in color to the 

 under parts. Lateral folds of tail white. 



In a young male 300 mm. long the spines above the eyes, those on 

 the l)ack and on the tail are present. Other parts of the body are 

 naked, the depressible spines on pectorals having not yet appeared. 



It is probable that those rays of "taille enorme" noted by Schlegel 

 are of some other species. 



Family DASYATID^. 



DASYATIS KUHLII (Muller and Henle). 

 Tokyo (Otaki). 



PTEROPLATEA JAPONICA Temminck and Schlegel. 

 Tokyo (Otaki). 



UROLOPHUS TULLBERGI Nystrom. 



Tokvo (Otaki). 



Family MYLIOBATID^. 



MYLIOBATIS TOBIJEI Bleaker. 



Tokyo (Otaki). MyUohatis cornutus Giinther is said to differ by 

 the presence of a horn over the eye. It is doubtless the same species, 

 the cutaneous horn being probably deciduous. 



Family CHIM.ERID^. 



CHIMiERA PHANTASMA Jordan and Snyder, new species. 



{Chimocra vionstrosa Temminck and Schlegel, not of Linnaeus. ) 



Mr. Otaki secured a specimen of Chimcera from the Bay of Tokyo 

 which differs from C monstrosa as described and figured by European 

 authors, in having much longer pectoral fins and larger eyes. It 

 differs markedly from 0. ogilhyi, an Australian form recently described 

 by Mr. Edgar P. Waite,^ in having a distinct anal fin, larger eyes, 

 and a longer dorsal spine.
