Fig. 1. A view, from below, of the mouth region of Eucalanus. The ap- 

 pendages and bristles are shown partly diagrammatic. On the left of the figure 

 are shown, from behind forward, the anterior maxilliped {ant. mxp.), the outer 

 lobe of the maxilla, the posterior antenna (post, ant.) ; on the right appear the 

 inner lobe of the maxilla (inxl.) with stiff, heavy bristles and the rami of the 

 mandible (mud.), the "jaw" being omitted. The shield-shaped promineuoe in 

 the center of the figure bears the scoop-like lip, within which is the opening 

 of the mouth (mth.). The side of the funnel formed by the bristles of the 

 anterior maxilliped is shown on the left of the figure, the other side being 

 omitted for the sake of clearness.
