All the above species except the deep water Culeolus herdmani 

 were collected at stations among the Philippine Islands. Although 

 only eight are new species, a majority of them have not been pre- 

 viously recorded from the Philippines. 



ADDITIONAL SPECIES COLLECTED BY OTHER EXPEDITIONS. 



To arrive at the total number of forms known from the Philip- 

 pines, the following list of species (25, with one very doubtfully 

 valid variety) previously recorded, but not collected by the Albatross 

 Expedition, must be added to the above 45. In order to avoid the 

 necessity of repeating this list, the synonyms of the several species 

 and the locality in the Philippines from which they have been re- 

 ported are also given. Leaving Gould's doubtful and insufficiently 

 characterized forms out of account, the species credited to the Philip- 

 pines number 70, representing 3G genera and 12 families. Among 

 these 70 species are doubtless some synonyms.
