the presence of scales 1 ). Mc. To tosh has been the 

 first, who demonstrated that Palmyra possesses smooth, 

 diaphanous scales, that were overlooked by Savigny, by 

 Audouin and Milne Edwards and by Grube. Considering that 

 Palmyra moreover agrees with Pontogenia in the appen- 

 dages of the head (stalked eyes, unpaired antenna), in the 

 shape of the ventral bristles and of the cirri with their 

 slender terminal part, then in my opinion there can nomore 

 remain any doubt, that Palmyra belongs to the Aphrodi- 

 tidae, as supposed by Savigny, and cannot be united with 

 Chrysopetalum, Paleanotus and Bhawania in the same family. 

 Therefore the family of the Palmyridae cannot longer be 

 maintained and, as already suggested by Ehlers, it is desi- 

 rable to use instead of that the name of Chrysopetalidae. 



This family may then be characterized as follows: 



Body short or elongated, with few or numerous segments, 

 all bearing on their dorsal side a fan or a transverse row 

 of paleae. Cephalic lobe provided with tentacles and eyes 2 ). 

 Buccal segment with two or four tentacular cirri on each 

 side. Parapodia uniramous or biramous, with dorsal cirri 

 upon all segments. Compound ventral bristles. 



A. Body short, with few segments. Parapodia uniramous. 

 a. Buccal segment with 4 tentacular cirri on each 

 side. Paleae arranged in a fan. 



Chrysopetalum Ehlers. 



Chrys. debile (Gr.) 3 ). 



{Palmyra debilis Gr. ; Chrys. fray He EhL; Palm, portus-veneris Clap.; 

 Palm. Evelinae Clap.; Chrys. coecum Langh.). 



Mediterr. (Nice, Porte- Vendres) ; Adriat. (Quarnero); 

 Madeira. 



1) About the distribution of the dorsal cirri there still reigns some uncer- 

 tainty; whereas Grube says that they appear alternately as with the Aphrodi- 

 tidae, according to Mc. Intosh „they occur both on feet provided with scales 

 and on those without them." 



2) I suppose that the palps in Paleanotus have been overlooked by Schmarda.
