Td.litfldae from Victoria. 31 



Lower lip. nieinbranous, lol)es wide, and broadly rounded 

 distally. 



First iiKixillae. — Inner jDlate narrow, extendinpf nearly to 

 the end of the outer plate, and tipped with two plumose 

 spinules ; outer-plate broad, and bearing apically a double series 

 of nine denticulated spines. Palp formed of one well-defined 

 minute joint, tipped with the vestige of a second one. 



Second inaxilhie. — Inner and outer plates broad and almost 

 of similar length to each other ; each fringed distally with 

 simple spinules, besides which the inner plate bears a long, 

 stout, feathered spine at the distal extremity of the inner 

 margin. 



MaiilJ ijjeds. —Outei- masticatory plates small, each broad 

 proximally, but rapidly narrowing to a bluntly pointed apex 

 directed obliquely inwards, and bearing, submarginally, a single 

 transverse row of short stiff set?e. Inner plates of usual form, 

 each bearing at the extremity two large teeth, and one small 

 one, also a few plumose setae. Palp of four joints, the ultimate 

 one being minute, and of conical shape, tipped with a long 

 spinule. It is usual for the members of this genus to have but 

 three joints in the palp, the fourth wanting or entirely coalescent 

 with the third, but in this species it is clearly marked off by 

 a distinct line of division from the previous one. 



GuatJiopoda. — First pair with carpus expanded distally. and 

 fully twice as long us its greatest breadth : propodus shorter in 

 length, and gradually narroAving to the dactykis. The second 

 pair agreeing in both sexes, of similar form to others of the 

 same genus, and without any specific characteristic. 



Pereiopoda. — -The first and second pairs similar to each other 

 and much longer than the gnathopoda. Third of equal length 

 to the preceding ones ; the fourth and fifth subequal in length 

 to each other, much longer than the preceding ones. Bases 

 of last pair Avidely expanded behind, with margin minutely ser- 

 rated. 



Pleopuda. — Only first and second pairs existing, and, as in 

 other terrestrial amphipoda, these are more or less atrophied 

 from disuse. Relative to the following species they are w^ell 

 developed — First pair very short with two well-developed 

 rami, the outer one (exopod) a little longer than the inner
