Boone, Mollusca, Cruises of "Eagle" and "Ara," 1921-28 207 



Technical description : Diagnostic description, including the 

 anatomy of this species, has been carefully reported by M. A. Vays- 

 siere in his "Recherches Zoologiques et anatomiques sur les Mol- 

 lusques Opistobranches du Golfe de Marseilles. Part III, Nudi- 

 branchs," p. 82. 



The development of this species has been studied by M. Viguier, 

 "Archives de Zoologie Experimentale, " 3me serie, tome VI, 1893, 

 pi. VII, fig. 1, and text. 



The "Ara" specimen is a large and strikingly beautiful one, about 

 14 cm. long. This species is readily recognized in the living state by 

 its distinctive coloration and by the large spotted appendages. The 

 fact that these latter break off easily if the animal is disturbed, have 

 caused them to be considered parasites by many people.
