built, with some of the setae spiniform. Last pair of legs, with the distal joint 

 spatulate in form, being conspicuously constricted at the base and broadly blunted 

 at the tip, which carries 5 setae, 2 of which are very small, hair-like; inner ex- 

 pansion of proximal joint broadly rounded, and provided with 4 slender, nearly 

 equal ciliated seta?. Ovisacs of moderate size. Spermatophore, attached to the 

 genital opening, unusually large, pyriform. 



Male, as usual, smaller than female, but having the caudal rami of ex- 

 actly the same shape. Inner ramus of 2nd pair of legs rather slender, biarti- 

 culate, distal joint gradually tapered and exserted at the end in a comparatively 

 short denticulated spiniform projection, outside which is a still shorter outward- 

 curving spine, inner edge carrying 4 somewhat unequal setae. Last pair of legs 

 with the distal joint very small and imperfectly defined at the base, proximal 

 joint forming inside, at some distance from the insertion of the distal joint, a 

 short conical lobe tipped with a slender seta. 



Colour pale yellowish. 



Length of adult female 0.52 mm. 



Remarks. It seems to me beyond doubt, that Prof. Brady under the 

 name of Delavalia reflexa has confounded two distinct species, some of the figures 

 given, especially those representing the 1st pair of legs and the male caudal rarni, 

 being unquestionably referable to a very different form, viz., Stenhelia longicau- 

 data Boeck, to be described farther on. The name reflexa proposed by Prof. 

 Brady for the present form is somewhat inappropriate, referring as it does to a 

 pecularity common to all the species of this genus, as also to some other Cope- 

 poda, viz., that in preserved specimens the posterior part of the body is often 

 found abruptly bent dorsally upon the anterior. The present species is especially 

 characterised by the form of the rostrum and the structure of the 1st and last 

 pairs of legs. In the living state it is moreover easily recognized by the pale 

 yellow colour of the body, for which reason, before recognizing its identity with 

 Brady's species, I had noted it under the provisional name 8. flavida. 



Occurrence. I have met with this species in 3 different localities of the 

 Norwegian coast, viz., in the upper part of the Christiania Fjord, at Farsund, 

 south coast of Norway, and at Bejan, entrance to the Trondhjem Fjord. In all 

 3 localities it occurred very sparingly at a depth of about 20 fathoms. 



Distribution. British Isles (Brady).
