bristles^ partly arranged in a double row. The 3 proximal 

 endites are, as in Eulhnadia, only represented by very slight 

 expansions of the inner edge of the stem, and are densely 

 fringed with slender setæ. The 5th endite is somewhat more 

 distinctly defined, though blunted at the tip, and carries a 

 long membranous stylet reaching to the end of the 5th endite. 

 The latter is less distinctly articulated to the stem, but of a 

 similar narrow, blade-like form as in Eiilimadia. The epipo- 

 dite, or gill, is not very large, and comparatively narrow, 

 tapering to an obtuse point. The exopodite is very fully 

 developed, and issues from the stem by a narrower base than 

 is the case in Eulimadia. Its proximal lobe is very distinctly 

 defined at the base, rather narrow, and projects far beyond 

 the epipodite. The distal lobe is likewise rather narrow and 

 reaches to the end of the 5th endite. Inside, this lobe exhibits 

 af its base a projecting setiferous lappet not found in Eidi- 

 madia. 



As in this genus, the proximal lobe of the exopodite in 

 the 9th and 10th pairs of legs is prolonged to a slender 

 filament, by the aid of which the egg-masses are kept in place. 

 The posterior pairs rapidly diminish in size, and exhibit a 

 similar reduction of the several parts as shown in the genus 

 Eulimadia. 



The egg-masses (see fig. 3) are apparently two, occurring 

 on each side of the body in the posterior part of the shell- 

 cavity. 



The eggs (fig. 9) are very small and perfectly globular. 

 Their envelope does not exhibit the peculiar sculpturing 

 charasteristic of the genus Eulimadia, but appear, when strongly 

 magnified, only minutely dotted. 



The colour of the shell in alcoholic specimens is a uni- 

 form dark brown,
