COMPARATIVE ABUNDANCE. 



The comparative abundance of the different species in the collection is readily 

 appreciated by a glance at the figures appended to the synopsis on page 260. It is remark- 

 able that out of a total of 210 specimens examined, 64, or nearly one-third, are Euprymna 

 scolopes. Of the remainder, 31 , or nearly one-sixth of the total, are Tremoctopus violaceus; 

 15 are the immature Polypus designated as /?; 13 are Polypus marmoratus; eleven are the 

 larval ommastrephids known as Rhyncoteuthion; 8 are Brachioteuthis riisei, while Scceur- 

 gus patagiatus and Ommastrephes hawaiiensis are represented by 7 specimens each. 



The most notable catch of cephalopods made by the Albatross in any single haul 

 was in the surface nets at station 3926, between Oahu and Laysan Islands, where 

 1 1 specimens representing 1 species each of no less than 5 genera were obtained. 



LOCAL DISTRIBUTION. 



Regarding the distribution and relative frequency of the littoral and shallow- 

 water species among the respective islands of the archipelago, little or nothing can be said 

 at the present time. As would be expected, most of the collecting has been done on 

 Oahu in the neighborhood of Honolulu ; a few specimens have occasionally come to hand 

 from Maui, but almost nothing from the other islands. The remote islands of the 

 Midway Group ought to prove particularly interesting in this respect, since their oceanic 

 extent is large and we are completely ignorant concerning the cephalopods of their 

 littoral fauna.
