Mil-, ii 111. iii (onus me that only five spines tire present on the lateral margin*, MI that 

 the armature of the telson of P. wirai approximates closely to that of P. Myica. 



The only other species of Pseudoinma having Hmooth ocular lamina it 

 P. australe, G. 0. San (1885), from Bass Straits, Australia. The vastly different 

 form of the antennal scale in the latter, however, abundantly distinguishes it from 

 P. Mgicat. 



Besides the single ' Discovery ' specimen, this species is also known from the 

 ' Bclgica' collections, and has been described by Hansen in MS. under the name which 

 is here used. It is possible that the mutilated specimen noted by Sara (1885, p. 191) 

 from 1675 fathoms in the Antarctic Ocean may have belonged to this species rather 

 than to P. sarsi Sars notes that it was much larger than the latter.

This genus was established for the reception of the single rather mutilated specimen 

 <>t />. /(. //..-/// in the present collection. Since the publication of the preliminary 

 notice of the 'Discovery' Schizopoda, however, two closely allied species have been 

 discovered off the west coast of Ireland (Tattersall, 1907). A clearer idea of the 

 exact relationships of the genus has thus been gained, and while the species referred 

 thereto appear, in the present state of our knowledge, to form a natural group, it w 

 undeniably very nearly allied to Dactylerythrops, Holt and Tattersall (1905), to 

 which genus, indeed, the present species was referred by Illig (1906). 



The definition of the genus given by Holt and Tattersall, 1906 (1), may therefore 

 l>e amended as follows : 



DACTYLAMBLYOPS, Holt and Tattcrsall. 



Characters generally as in AnMynps, G. 0. Sars, except : 



Eyes placed close together, but not contiguous, more or less pyriform in shape, 

 furnished with distinct and definite peduncles ; visual element* imperfectly developed, 

 numerous, reaching to the surface of the eye, and probably directly functional as 

 organs of sight ; outer distal corner rounded, and not produced into a digitiform 

 process ; a short blunt process always present on the inner and upper surface. 



Second thoracic limbs with the endopods not noticeably short, but well developed, 

 and considerably longer than the endopods of the first thoracic limbs. 



Tebnii not very long, triangular in shape, the distal part* of its margins armed 

 with more or fewer spines ; median sefoe absent. 



Type species, D. hodgsoni, Holt and Tattersall.
