The genotype is an adult female with fuUv developed 

 eggs in the two distal coxse and femora of all the legs. 



So far as can be made out (with exception of the 

 ovigers referred to in the description of the species) Has- 

 well's specimen agrees with Loman's definition of the 

 genus. , 



Genus Nymphopsis includes the following species : — 

 Nymphopsis armatus, Haswell, 1884, p. 1025, Port Molle, 



15 fathoms. 

 Nymphopsis korotneivi, Schimkewitsch, 1887, lies de la 



Sonde, East Coast of Timor, 34 metres. 

 Nymphopsis mtiscosus, Loman, 1908, East Indies, 16-130 



metres ; Japan, 50-130 metres. 



Nymphopsis armatus, Haswell.

Specimen. — Australian Museum Collection, G5201, 

 holotype, female. Port Molle. 



Description. — Trunk is quite smooth tubular and toler- 

 ably slender. The portion behind the third pair of cruri- 

 gers is narrower than that in front. Seg'mentiation is abso- 

 lutely sup-pressed. Grurigers are well separated at the base 

 and diverge towards their extremities. The posterior pair 

 extend almost directly backward. Each cruriger is distal- 

 ly expanded with a single dorsal spine. 



Gephalon is very small. 



Ocular tubercle is situated on the level of the first pair 

 of crurigers and arises by a wide base narrowing above to 

 form a fairlv high almost perpendicular tube terminating 

 in a bluntly conical apex. The eyes are large and strongly 

 pigmented, the posterior pair being the smaller. 



Proboscis ia of large size. It arises by a wide base on 

 the ventral side of the trunk at the level of the first pair of 

 crurigers. It projects diagonally downwards. Its shape 

 is that of an ellipse with the narrower end forward and 

 tru.ncated.
