 the common form of ichthyosis in which the whole 

 surface has a tesselated appearance, from being covered 

 with large, angular, dirty- white, finely corrugated, 

 papery scales that are adherent, and therefore slightly 

 depressed in the center (/. scutellata), while the edges 

 are detached, transparent, and shining (/. nacree or 

 /. nitida). In still higher grades the scales adhere 

 together to form thin plates, and being of a greenish 

 tint, resemble a serpent's skin (/. serpentina) ; when 

 there are still thicker plates, the appearance of a 

 crocodile hide is produced (/. sauroderma). The 

 older the plates the darker they become, so that they 

 may vary from olive-green to black (/. nigricans). 

 The hair is dry, harsh, and dull-looking, and the 

 scalp branny ; the nails may be pitted and brittle. 

 Itching is frequent. Warmth ameliorates the condidon 

 by favoring sweating. I. spinosa, a form of I.
