close together but not cuiitiguous, beuriug on the inner dorsiil 

 face a short digitate process ; visual elements imperfectly 

 developed. 



Telson without median sctiC. 



Second thoracic linihs with the endopods well developed 

 and considerably longer than the endopods ol" the first liniljs. 



Type species, D. Hodysoni. 



As far as can be judged from Ohlin's description and 

 figures of Amblyops Sarsi (Ohlin, 1901), that species should 

 also be included in Dactijlnnihlyops. 



Dactylamhlijops Hodysoni, ap. u. 



Form as usual in the genus Anihlyops, Carapace sub- 

 mcmbranaeeous, covering all the thoracic segments except the 

 last; cervical sulcus well marked; evenly lomided in front 

 and at the antero-lateral corners. Ei/cn rather small, placed 

 close together in the median line, but not in any way con- 

 tiguous ; pyriform in shape, front end evenly rounded; 

 a short digitate process arising from the inner dorsal face ; 

 visual elements imperfectly developed, apparently represented 

 by minute granular bodies having a refractive centre. P/eon 

 Avith the first five segmenis subequal in length, the sixth 

 nearly twice as long as the fifth. Antennnles, antennoi, and 

 scale missing in the specimen. Mandibles and ma.villa not 

 exhibiting any salient points of difference from those of 

 Amblyops ahireviata. First thoracic limb with endopod of 

 the same size and general structure as in A. ubhreciata. 

 Second thoracic limb with endopod slender and about twice 

 as long as that of the fir.>t. I'leopods in the male agreeing 

 essentially with those of the niaUs of the genus Amblyops. 

 Telson not quite as long as the last segment of the pleon, 

 triangular in sha[)C, tapering evenly to a narrowly rounded 

 apex and about twice as long as it is broad at its base; the 

 distal half of each lateral margin bearing about nineteen 

 spines gradually increasing in length towards the apex ; 

 terminal spines about one tenth of the total length of the 

 telson ; median setae absent. Uropods broken in the specimen. 

 Length of the single specimen, a male, 13 mm.

'J'liis species may be distinguished from its nearest ally and 

 probable congener, Amblyops Sarsi, Ohlin, by the eye, which 

 in the latter appears to be sharply pointed in front ; and by 

 tlie telson, Mhich Ohlin describes in A. Sarsi as having the 

 distal half of the lateral margins fringed with short seta.
