12 CATALOGUE OF MADREPORA CORALS. 



species, the writer beiug unable, in fact, to identify more than one of 

 the species with certainty. It has been thoufjht best, however, to defer 

 reference to these species until a more careful comparison can be made 

 with other collections than our own. Two other species of doubtful 

 identity have also been contributed by Dr. W. H. Jones, U. S. N., from 

 Palmyra Island, in the Pacific Ocean. 



In the following list the species have been arranged in alphabetical 

 order, without regard to their relations, as affording the most conven- 

 ient means of reference. A mark of interrogation, thus (?), before the 

 name of a locality indicates that the identity of the specimen is in ques- 

 tion ; after a locality, that the latter is in doubt. The numbers under 

 which the specimens are recorded in the catalogue books of the National 

 Museum are given in parentheses following each citation of locality and 

 collector.
