An undetermined species of tick (odes) was recorded by Hurdis 
(Rough Notes, p. 328) as found in large numbers on the leg of a 
heifer. It was white and the size of a pea. Mr. Nathan Banks,*

undetermined species of Rhyncholophus and Holostaspis as found in 
our collection. A species known as the Kucharis-mite (Rhi- 
zoglyphus echinopus) occurs on the diseased bulbs of the Easter Lily, 
and is supposed to be one of the causes of the disease. A mite 
* Mr. Banks has determined all the mites and spiders in our collections.
