A Skin (integument) and derivatives, in toto . (This excludes actual hard, completely 



enveloping exoskeletal structures of arthropods, coelenterates [corals], and Protozoa 



[Foraminifera], e. g. , though integument tissues secreting these supportive coats are 



included. For the exoskeletal structures, use a symbol of the 9-- series. ) Use 



Symbol A to code the organism's surface, in toto .

for beak, in toto , use Symbol 927. ) 

 D16 Sudoriferous gland (= sudoriparous or sweat gland) 



(B) Body regions. (Use Symbol A to code the organism's surface, in toto . Symbol B is used 



to refer to the organism's mass and surface. For example, Symbol Bl refers to the entire 



mass [and surface] of the head, etc. )
