610 " THETIS " SCIENTIFIC RESULTS. 



Sars is entirely wanting, the palm is less oblique and defined by 

 A moderately strong tooth with adjacent spine. Between this 

 and the finger hinge are two small processes separating shallow 

 excavations. 



The peraeopods are of the character usual in the genus, but 

 the side-plates of the third pair seem to differ by having the 

 width (true length) of the deep front lobe much less than usual 

 relatively to that of the hind lobe. The second joint of the third 

 peraeopods is nearly circular and strongly fringed with setse on 

 both margins. The backward-turned finger is as usual opposed 

 to a strong spine projecting from the preceding joint and carries 

 behind its nail a spine so strong as to give the finger an appear- 

 ance of being apically bifid. The same structure, however, is 

 repeated in th^ two following pairs, but on a scale successively so 

 dwindled that the little spines might easily pass unobserved. 

 As in other species the fourth pair are longer than the third and 

 the fifth than the fourth, with the breadth of the second joint iu 

 comparison with its length successively diminishing. 



The pleopods have very small coupling spines. The inner 

 ramus is rather longer than the outer, though it has one joint 

 less, the number of joints being respectively nine and ten, as 

 counted in one pair. 



In all the uropods the peduncle is longer than the rami, 

 especially so in the first pair. As already noticed the second 

 joint of the outer ramus in the third uropods is very diminutive, 

 the inner ramus is about one-third as long as the outer. The 

 telson is small, triangular, rather broader than long, with the 

 customary spinule and setule springing from the surface a little 

 above and on each side of the apex. Length at full stretch about 

 7*5 mm. from apex of eye to apex of telson; first antennje 

 attaining a length of 6 mm. 



The specific name, from 8o\ix6s, long, and o/x/xara, eyes, refers 

 to those features as described.
