figured as if pressed against its lower -urfacr. The large anterior 

 Byee with their latero-ventrally directed lenses occupy a considerable 

 part of the ventral surface. Posterior and ventral to these are the 

 palp- with their two portions nearly equal in -i/.e. hanging down 

 so as to COTer the sides of the mouth. While in the ligiire they are 

 shown under slight pre--ure. their direction is only very slightly 

 changed by it. 



The jaws have each a large terminal and live smaller lateral teeth. 

 I could discover no trace of paragraths. 



The dorsal cirri of the first seven somite- are enlarge.!, increasing 

 succe ively in size until the seventh is reached (fig. 3 of the 



seventh). The notopodium 

 has two obtuse subequal 

 lobes, the acicula extending 

 into a short conical lobe 

 between them. The neuro- 

 podium has a dorsal coni- 

 cal lobe, into which the 

 acicula extends, and an 

 obtuse ventral lobe similar 

 to that of the notopodium. 

 Dorsal cirrus elongated, 

 its terminal portion bent 

 and slightly flattened as 

 shown, somewhat fore- 

 shortened, in the figure. 



Setae of notopodium 

 with long " camerated " 

 shafts, the terminal joint 

 set into rather a deep 

 socket. The terminal joint 

 is long, slender, and very 

 sharp pointed, with nu- 

 merous very sharp teeth 

 along the greater part of 

 one edge. The teeth are 



all drawn out into fine processes, which bend apically so that each 

 covers over several of those distal to it. In the ventral bundle are a 

 few similar to the dorsal and others having the terminal portion 

 short, narrow as compared with the basal joint, with one large tooth 

 at the apex and a row of very line teeth along one margin. 



The para podia, from eighth to fourteenth inclusive, are unmodified, 

 though the general structure of neiiropndium. notopodium. ventral 

 cirri, and setae are essentially as in the -e\enth. The dorsal cirrus 

 is much shorter and tapers slowly to a blunt end.
