Dr. Weidman's Report. 
Of the 339 animals autopsied this year 44 showed 
worms of one kind or another, a percentage of 12.9. 
The number is exactly the same as for last year for which 
there was a percentage of 11.4. There were two small 
special groups of worms occurring in special animal 
groups, i. e. Uncinaria in Carnivora and Tropidocerca in 
cranes and a flamingo. The latter worms are non- 
pathogenic in spite of their blood-red color and position 
deep in the proventricular crypts, for our concave- 
casqued hornbill has passed ova of this genus for five 
3^ears and appears well. The uncinaria cases were in 
wild cats and ocelots which had been in the garden not 
longer than three months in any case and were therefore 
certainly infested upon arrival. 
Two papers have been contributed this year on parasito- 
logical subjects. The first was published in the Journal 
of Parasitology 1916, Vol. Ill, No. 2, page 82 entitled 
^'Cytoleichus penrosei*, A New Arachnoid Parasite 
Found in the Diseased Lungs of a Prairie Dog, Cynomys 
ludovicianus". It described an arachnoid of importance, 
since it produced a fatal broncho-pneumonia. Similar 
organisms have been found by AVellman and Wherry in 
the lungs of California ground squirrels. The parasites
