Colour of female light yellow. 



Length of adult female 1.30 mm., of male 0.90 mm. 



Remarks. Though the description and figures of this form given by 

 Scott are rather imperfect owing to the bad condition of the specimens ex- 

 amined by him, I cannot doubt that the above-described form is the same. 

 Scott had some doubt about its right position within the genus Hermannella, 

 and indeed in some points it differs conspicuously from the typical species 

 H. rostrata Canu, especially as regards the structure of the 4th pair of legs, 

 the inner ramus of which is much fuller developed than in that species. But 

 otherwise I find that it agrees fairly well with the other species here described. 



Occurrence. I have met with this form occasionally both off the west 

 and south coasts of Norway in moderate depths. The specimens examined 

 by Scott were collected by Canon Norman, in Bug0 Fjord, East Finmark. It 

 thus appears that this form is destributed along the whole Norwegian coast. 

 Out of Norway, however, it has not yet been recorded.

 (PI. CII). 



Specific Characters. Female. Body rather slender, with the anterior 

 division regularly oblong oval in outline, greatest width scarcely exceeding 

 half the length, and occurring about in the middle. Cephalic segment about 

 twice as long as the 3 succeeding segments combined, and exhibiting behind 

 a well-marked transversal suture, frontal margin narrowly rounded. Last trunkal 

 segment, as in the 2 preceding species, exhibiting on each side, behind the 

 insertion of the free joint of last pair of legs, a dentiform projection. Tail 

 very slender and attenuated, considerably exceeding half the length of the 

 anterior division; genital segment about the length of the 3 succeeding seg- 

 ments combined and considerably dilated in the middle. Caudal rami long 

 and narrow, fully equalling half the length of the remaining part of the tail, 

 and slightly divergent; seta of outer edge placed about in the middle and 

 somewhat dorsally; apical setae comparatively less elongated than in H. fin- 

 marchica. Anterior antennas more slender, equalling in length the cephalon. 

 Posterior antennae very like those in the said species, though having the apical 

 claws still more slender. Maxillae with the masticatory lappet rather large and 

 finely serrate along the outer edge, the proximal serrations rather coarse; palp 

 with 1 lateral and 3 apical setae. Anterior maxillipeds with the terminal process 

 less curved than in H. finmarchica and having the proximal spinule much
