Differing from its nearest ally, V. vigourouxii, in the peculiarity 

 of the epidermis and in the anterior part of its aperture being more 

 rounded and not nearly so dilated ; there is also no callosity near 

 the margin of the inner lip ; the difference in size is equally very 

 great, V. rn/ourou.vii being 24 mill, in length and 14* in breadth. 

 The animal resembles that of V.fragilis Pease, the color being bright 

 orange with bands of red aggregated corpuscles ; it lives in shallow 

 water on reefs among corallines, etc. ; when molested exudes a 

 milky fluid (New.*).
