inner expansion of same joint only represented by a small conical projection 

 tipped with 2 setae. Ovisac comparatively small, rounded. 



Male, as usual, considerably smaller than female and having the anterior 

 antennae slightly transformed and adapted for prehension. Last pair of legs 

 resembling in shape those in female, but still smaller and having only a single 

 seta inside the proximal joint. 



Colour whitish, pellucid, with a few irregular patches of a clear orange hue. 



Length of adult female 0.93 mm., of male 0.70 mm. 



Remarks. In its outward appearance this form has a general resem- 

 blance to Stenocopia setosa described in the main part of this work, and at 

 first, therefore, I was inclined to refer it to the same genus. A closer ex- 

 amination has however proved it to differ so materially in some of the structural 

 details, that it can scarcely be included in that genus. 



Occurrence. This peculiar Copepod occurred not unfrequently in the same 

 locality as that in which Stenocopia spinosa and many other interesting forms were 

 found. It could at once be distinguished from Stenocopia setosa, which also occurred 

 in the same locality, by its comparatively short and peculiarly formed caudal rami.

Male. Rather unlike the female in its outward appearance, the body 

 being more rapidly attenuated behind, with the segments of the urosome simple 

 cylindrical in form. Caudal rami much more produced than in female, equalling 

 in length the last 2 segments combined, and very slender, gradually tapered 

 distally, apical seta not, as in female, bulbously dilated at the base. Anterior 

 antennae very strongly built and composed of only 7 joints, those belonging to 

 the proximal part considerably dilated. Legs comparatively less slender than in 

 female, especially those of 4th pair. Last pair of legs very unlike those in 

 female and of much smaller size, each composed of 2 well defined joints, the 

 proximal one somewhat lamellar, conically produced outside, and forming inside 

 a well defined, though short expansion carrying 3 spiniform setae, distal joint 

 rather narrow and projecting at the end outside to an acute point, outer edge 

 straight and carrying 2 small bristles, inner edge armed at about the middle with 

 a strong spiniform seta and at the end, inside the apical point, with 2 somewhat 

 smaller setae. Genital lobes each with a strong spine and 2 unequal setaa. 



Length of adult male 0.60 mm.
