on the basis of these intermediate specimens was discarded. Since 

 these intermediate specimens .were taken over a wide area including 

 certain islands of the East Indies, Philippines, and Solomons, one must 

 assume that they represent intergrades between two forms occupying 

 different habitats. A search for ecological data from the literature 

 and Albatross records revealed no relationships between color form 

 and habitat, nor were any significant differences found in habitats oc- 

 cupied by the four species. It is suspected that color differences owing 

 to sexual dimorphism may exist in handaneTisis and this factor may, 

 in part, be associated with these intermediate-colored specimens. 

 More study with freshly collected material from the East Indies and 

 Philippine Islands is required. 



A. savayensis probably attains the largest average size of this 

 group, reaching a maximum length of about 80 mm. The young 

 appear to be more elongate and less deep than the young of the other 

 three species.
