4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 1 39 



The patterns of coagulation have been represented in the table by 

 the following symbols : 



$ : pattern I : inception of the plasma coagulation in the shape of 

 islands of coagulation around the unstable hyaline hemo- 

 cytes. Various degrees of extension of the process in the 

 films. 



O : pattern II : development of cytoplasmic mesh works by hyaline 

 hemocytes. Reaction in the plasma in the shape of veils. 



O-: pattern II incomplete: emission of cytoplasmic expansions, 

 characterizing the reactions of the hyaline hemocytes in pat- 

 tern II, but unaccompanied by formation of veils in the 

 plasma. 



(•): pattern III : patterns I and II combined. 



— : pattern IV: no visible coagulation by phase-contrast micros- 

 copy. 



( ) : pattern incidentally or exceptionally recorded in limited fields 

 of preparations exhibiting predominantly another pattern. 



( ?) : microscopical characters of a pattern not clear-cut or equivocal. 

 Artifacts possibly involved. 



Other abbreviations used: sp., species; spm., specimen; T., speci- 

 men captured and studied at Tingo Maria ; B., specimen captured and 

 studied on Barro Colorado Island. 



Gradations in the intensity of the reactions, especially with regard 

 to pattern I, are indicated by the following symbols: I poor (scarce 

 fringes of clotted plasma around a limited number of altered fragile 

 hyaline hemocytes, without extension of the coagulation; I (scattered 

 islands of coagulation of various sizes, with moderate coagulation of 

 the fluid outside the islands) ; I*, I**, I*** (islands around all the 

 hyaline hemocytes, substantial and general coagulation of the film).
