Cerrinia synartlira, G. 0. Sars, n. sp. 

 (see below). 



Cervinia Bradyi, Norman. 



(Suppl. PI. 1) 



Specific Characters. Female. Very similar in its external appearance to 

 C. synarfhra, but of somewhat smaller size, and having the caudal rami comparatively 

 shorter and more divergent; apical setae curving abruptly outwards and densely 

 ciliated in their outer part. Antennae and oral parts almost exactly as in the 

 said species. 1st pair of legs likewise very similar, though having the inner 

 ramus fully as long as the outer. The 3 succeeding pairs of legs, however, 

 differing conspicuously in the structure of the inner ramus, which is distinctly 

 3-articulate, with the last 2 joints not, as in C. synarthra, fused together, but 

 well defined. Last pair of legs very small and of a structure similar to that in 

 the said species. 



Male differing very conspicuously from female in its external appearance, 

 being on the whole of a more slender form, with the anterior division regularly 

 oval in outline and marked off from the posterior by a distinct constriction. Ce- 

 phalic segment much narrower than in female and produced in front to a very 

 large and prominent rostral plate of triangular form. Epimeral plates of the 3 

 succeeding segments not, as in female, laterally expanded, but deflexed, each 

 terminating behind in an angular corner. Urosome (including the caudal rami) 

 about the length of the anterior division, and somewhat tumid in its anterior part, 

 and being thickly covered with small spikes. Caudal rami much more prolonged 

 than in female, attaining the length of the 3 last segments combined, apical setae 

 straight and very minutely ciliated. Anterior antennae imperfectly hinged, but 

 more strongly built than in female, with the joints more sharply marked off from 

 each other, and also of a somewhat different shape, 2nd, 3rd ad 4th joints each 

 carrying an exceedingly large recurved sausage-shaped sensory appendage of a 

 very delicate hyaline appearance. Posterior antennae comparatively more feeble in 

 structure than in female. Oral parts likewise considerably reduced in size. Na- 

 tatory legs of essentially the same structure as in female, the inner ramus in all 

 of them being distinctly 3-articulate. Last pair of legs, as in female, biarticulate 

 and scarcely smaller in size. Genital lobes each with 2 spiniform setae. 



Body (in female) of a clear yellowish colour, variegated in front with 

 light orange ; urosome of a more or less vivid brimstone-yellow.
