SOLBNOCERA COMATUS, n. Sp. 



Plates LXXVIL, LXXVIII. 



The carapace is scabrous, the rostrum directed straight forward, 

 only twice as long as deep, the medio-dorsal carina having a tooth 

 just in front of the cervical groove, followed by a series of four 

 teeth of which the hindmost is just behind the base of the orbit and 

 the foremost separated by a distinct interval from the apical point ; 

 below this point the margin descends with a gentle curve adorned by 

 a conspicuous series of plumose setae, to which the specific name 

 alludes. Behind this series the lower margin of the rostrum, is 

 horizontal. The sides of the carapace have an antennal tooth and 

 an antero-lateral, and on the surface a tooth a little above and behind 

 the antennal with an apex not quite reaching the margin, and a 

 tooth at the lower end of the cervical groove. The fourth, fifth, and 

 sixth pleon segments are carinate, the sixth ending in a distinct 

 tooth. The telson is shorter than the uropods, ending acutely, for 

 nearly two-thirds of its length to the rear fringed with plumose 

 setae, the last third narrow, with a pair of slightly divergent 

 processes at its base which are not quite half its length. 



The eyes are brownish red, short, with large oval cornea, pro- 

 tected by the first joint of the first antennae, this joint being as long 

 as the second and third joints combined and having two small 

 lateral teeth. The flagella are not quite twice the length of the 

 peduncle, one flagellum about two-thirds the breadth of the other. 

 In the second antenna the apical tooth of the scale reaches just 

 beyond the setose margin ; the flagellum (imperfect) considerably 

 exceeds the length of the body. 



The rnandibular palp is very large and setose, with a twist at the 

 base of the first joint, which is decidedly wider and not shorter than 

 the long second, that being wide at the base, distally quite narrow. 

 The plates of the lower lip are in close contact, longer than broad.
