Twenty-four New Species of Botifera. By P. H. Gosse. 7 



Nearly related to the preceding ; but the outline, viewed dorsally, is 

 longer and narrower; there is no protrusion of the body behind the 

 lorica; and the toes are quite straight. The frontal hook is unusu- 

 ally narrow. I have not been sure of an eye. A dozen examples have 

 occurred from the Tay tide-pools. (Fig. 23.) 



24. Monura micromela. Lorica in dorsal aspect broadly ovate, 

 produced behind into slightly projecting points, separated by a shallow 

 rounded sinus : in lateral aspect the quadrant of an oval : foot small ; 

 toe single, of uniform excessive tenuity. Length 1/230 in. Lacustrine. 



I have had, for thirty-six years, drawings of a species which I had 

 marked (with " ? '"), as Monura dulcis. Yery recently, in water from 

 Slough, what seems the same form, now figured, has occurred, and 

 that repeatedly. The excessive tenuity of the toe, which seems indi- 

 visible, is the most striking feature ; and then the round sinus between 

 the lorica-points {m). No eye is visible. The general figure is that of 

 Col. hicuspidatus. (Fig. 24.)
