KEPORT ON THE SCHIZOPODA. 



lOi 



above and drawn ont to a strong spinr. Antennal scale oblong-ovate ; apex rounded, with 

 no denticle on outer corner. Penultimate pair of legs much shorter than preceding. 

 Telson wdth numerous small dorsal denticles. Inner plate of uropoda scarcely shorter 

 than outer. Length 15 mm. 



Remarks. — Of this form, not recorded in my Preliminary Notices, the collection 

 contains a single, apparently young, specimen, stained with carmine and mounted on a 

 glass slide. It is somewhat defective, wanting, as it does, several of the legs, as also the 

 outer part of the telson. Quite recently I have, however, had an opportunity of examining 

 another sjaecimen of the same species, in an excellent state of preservation, brought home 

 by the Norwegian traveller, Mr. Lumholtz. I have tlius been enaVded to make out the 

 distinctive characters with greater pi'ecision, and at the same time been fully convinced 

 that the form in question constitutes a new and well-marked species of the genus

TJiysanopoda. Owing to the species not being figured in the plates, I have subjoined a 

 woodcut, exhibiting the Challenger specimen from the riglit side. This form is closelv 

 allied to Thysanopoda ohtusifrons, from which, however, it may be at once distinguished 

 by the sharply pointed rostrum and the well-marked lateral denticle of the carapace. 

 Moreover, its specific designation is derived from tlic remarkably small size of the eyes. 



Description. — The Challenger specimen has a length of 1 5 mm. That secured by 

 Mr. Lumholtz, which appears full grown, is considerably larger, measuring about 2-2 mm. 

 in length. Both specimens are females. 



The form of the body (Fig. 3) appears somewhat more slender than in any of the 

 preceding species. 



The carapace has on either side a well-marked lateral denticle, extending from the 

 inferior margins far behind the middle, or, more precisely, just above the base of the 

 penultimate pair of legs. Its anterior part is veiy slightly keeled above, and projects
