(loncral conclusions regarding the correlation between temperature and the 

 distribution of the species of Madraporarla around the Hawaiian Islands: 



Temperature 78°-73° F. — Seventy-seven of the 124 forms recognized live within 

 these temperatun; limits and at a depth of less than 4(1 fathoms. 



Teiiip' nitiirr 7->-G0- F. — Nineteen forms live between these limits. These 

 form,s should be dividid into two temperature zones: F/'rsf, between 73'^ and 70°, 

 in which 4 s])ecies occur, namely: Faii(//,(i patidla (Ellis and Solander), Fmu/ia 

 _/'/•«;/ ///-y (Alcock ). Lc/itiixi'Ttn hawaliensix Vaughan, and Leptonerls sccdira Vaughan. 

 The first two were found only within tluise tcMuperature limits and only at a depth 

 between 40 and 7"> fathoms. L,-pf<ixrrix lidinai.icuKis ranges in depth from about 2.5 

 fathoms to over 2;")(i fathoms, in temperature from 4tI.S'^ to 73.7 ; L. scahra in depth 

 from about 2.5 to nearly 80 fathoms, in temperature from 61^ to 74-. Second, 

 between 60'^ and 70'', none of the remaining forms, possibh^ excepting Bahtno- 

 phyllui deKiiMphyllioidex Vaughan, which may have lieen found at a temperature as 

 high as 77- F.. was collected at higher tcniperafurc than 09-" F.
