MYCOSIS 565 
California Hair Seal {Zalophus californianus) 9 • Had sore spots 
on side for several months. Ate well up to three days before death 
but ate something to time of death. 
Diagnosis. — Chronic enteritis with acute hemorrhagic exacerbation. 
Low grade chronic diffuse nephritis. Botryomycosis. General condi- 
tion poor, subcutaneous fat practically absent. On the left side of the 
thorax there is a warty and nodular thickening of the skin overlying 
diffuse and flat thickening of subcutaneous tissues. There are warty, 
pustular, fistulous communications in four places between surface and 
deep mass. They are covered over with light crust. On dissection 
mass is found to be in subcutaneous tissue well outlined and encapsulated 
and consisting on section of dense, white, firm trabeculae forming a 
mesh around yellow, soft areas which can be squeezed out. An adjoin- 
ing lymph node is much enlarged, dense, tough, resilient, on section 
showing great connective tissue increase and solid brown medulla. The 
thyroids are solid, brown, 3. x 2. x .6 cm. and 3.7 x 1.8 x .6 cm. Trachea 
and bronchi contain pink froth but mucosa is negative. Anterior edges 
of lungs are distinctly emphysematous. Remainder of lung is uni- 
formly congested and lobules are quite prominent. No consolidations. 
Bronchial lymph nodes are slightly large, anthracotic and wet. The 
heart is dilated, filled with mixed clot, muscle firm and deep brown 
color. The liver surface is smooth, edges sharp, size normal, color 
dull brown with greenish east, consistency firm and tough. Section 
surface is glistening, smooth, moist, lobules indistinct but probably 
normal. The gall-bladder is full of fluid yellow bile. The common 
duct is patulous. The spleen is of normal size and shape, capsule opaque 
gray. The trabeculae are prominent, the pulp stippled rusty brown. 
The kidney is of normal size, capsule is smooth, strips easily leaving a 
smooth purple surface. The organ is flnn. The lobules and lobular 
markings are distinct. The adrenal has a narrow regular brown cortex 
and gray homogeneous medulla. The stomach contains whole fish. 
The mucosa shows digestion, congestion and mucus formation. Begin- 
ning at the pylorus and extending to the colon the mucosa is swollen 
and edematous, yellow brown. In the lower part it is quite firm and 
opaque. In the upper part it is more translucent except where there 
are diffuse hemorrhagic mottlings of the submucosa. Here and there 
are shallow erosions but no ulcers. The lymphatics of the mesentery 
are definitely enlarged, white, pale and vei-y firm. Smear from the 
surface of the growth in side fails to show any definite yeasts or moulds 
by Loeffler's or Gram's stains. It is largely made up of polynuclear 
cells with many large mononuclears, many of which are phagoeyting 
polynuclears and nondescript bodies. Cultures failed to grow. Micro- 
scopic section of liver shows marked congestion with slight hydropic 
degeneration of the epithelium. The kidney capsule is not thickened. 
Interstitial tissue not grossly exaggerated but connective tissue nuclei 
fairly numerous. Some tufts have decidedly more enlongated nuclei
