 palp minute, obscurely 2-joiuted. 



Maxilliped, inner plate very narrow, apex obtuse, outer plate ovate, 

 palp slender, 2nd joint longest, 3rd and 4th subequal, but 4th more 

 slender than 3rd, 4th joint with 1-2 very fine apical setules. 



The other mouth parts could not be dissected out satisfactorily on 

 account of the state of preservation. 



First gnathopod, 2nd joint as long as rest of limb, 6th transversely 

 oval, in shape moi-e like that of T. nicaeense than T. raschi, reversed in 

 one specimen, not in the other, anterior (in untwisted position) margin 

 a little shorter than palm, which is 1 Mimes inferior margin, palm very 

 slightly convex, with 5 small spines on margin and 4 larger ones 

 within the margin, 3 unequal spines at junction of palm with hind 

 margin, finger strongly curved, just exceeding palm in length. 



Second gnathopod slender, 2nd joint equal to 4th, 5th and 6th 

 joints together, 3rd and 5th subequal, 4th and 6th subequal, 5th 

 cylindrical, not swollen, with dense spreading tufts of setae, 6th 

 oblong, not expanded, longer than broad, also with tufts of setae, 

 finger small. 



First and second peraeopods, 2nd joint equal to 3rd and 4th 

 together, 4th with 3 spinules on anterior margin and 1 at apex, 5th 

 and 6th joints subequal, but 6th only half width of 5th, 5th with 

 5 spiuules on anterior margin and 1 at apex, 6th likewise, finger 

 I length of 6th. 



Third to fifth peraeopods becoming progressively longer, 2nd joint 

 expanded posteriorly, on 3rd peraeopod only a very little longer than 

 broad, on 4th a little longer than broad, on 5th 1J times as long as 

 broad, but abruptly narrowed near base, hind margin nearly straight 

 with a few indents, 4th joint of 3rd peraeopod with 2 spinules on 

 anterior margin and 1 on apex, of 4th peraeopod with 4 and 1 respec- 

 tively, of 5th peraeopod with 5 and 1, 5th joint of 3rd peraeopod with 

 4 and 1, of 4th peraeopod with 6 and 1, of 5th peraeopod with 9 and 

 1 respectively, the anterior apex of 5th joint on each peraeopod pro- 

 duced into a sharp triangular process, anterior margin of 6th joint of 

 3rd peraeopod with 5 spinules, of 4th peraeopod with 5, and of 5th 

 peraeopod with 7, inner margin of finger finely serrulate. 



First uropod, outer ramus shorter than inner, outer margin with 

 5-7 deep indents, each with a spinule at its base, outer margin of 

 inner ramus with 1 or 2 such indents near apex, inner margin with 3 

 spinules near base, whole of inner and outer margins of inner ramus 

 and inner margin of outer ramus in addition finely serrulate. 



Second uropod shorter and more slender than 1st, rarui subequal,
