Miscellaneous. 313 



Skull resembling that of the young of the larger species, with the 

 tympanic case not produced backwards. The smallest species. 

 Testudo micropliyes (Grthr.), from Hood's Island. 



Part III. will contain the account of the still existing Tortoises 

 of the Mascarenes, and Part IV. that of the extinct species. 



Received June 9, 1874. 



P.S. The author has just received from Professor Huxley the 

 carapace and skeleton of another adult male, which evidently 

 belongs to a fifth species of Galapagos Tortoises. With regard to 

 the form of the carapace, it resembles much that of T. elejphantojms, 

 the dorsal shell being depressed, broad, with the upper profile 

 nearly horizontal. Stria? distinct, broad. However, the skull 

 differs widely from that of T. elephantopus, and has all the charac- 1 

 teristics of that of T. ephippium, from which it differs in having 

 a circular tympanic opening. The form of the sternum is quite 

 peculiar, the gular portion being much constricted and produced 

 forwards, whilst the opposite end is expanded into the large anal 

 scutes and deeply excised. This species may be named Testudo 

 vicina. 



MISCELLANEOUS. 



On tlie Annelids of the Gulf of Marseilles. By M. A. F. Marion. 



I have the honour to submit to the Academy the principal results 

 of the researches on the Chsetopod annelids of the Gulf of Mar- 

 seilles, which I made in conjunction with M. Bobretzky, of Kiew, 

 during the winter of 1873-74. We have been able to determine 

 ninety-six species, among which ten appear to us to be entirely new 

 to science ; for four of them we shall even have to establish new 

 generic divisions. 



Of the eighty-six known species which we have observed, and of 

 which we have completed our study, eighteen exist in the Black Sea, 

 or are represented there by forms which can only be regarded as 

 local varieties or as subspecies of more or less importance. These 

 are : — 



Plioloe synophthalmia. Sy Hides pulliger. 



Eunice vittata. Eteone picta. 



Lysidice ninetta. Eulalia virens. 



Staurocephalus rubrovittatus. pallida. 



Nereis Dumerilii. macroceros. 



cultrifera. Audouinia filigera. 



Syllis gracilis. Folyophthalmus pictus. 



spongicola. Aricia (Erstedii. 



Trypanosyllis Krohnii. Saccocirrus papillocercus. 



We find also seventeen of our Marseillese species in the lists of
