is recorded in the following table, was about three-fourths engorged, 
having been collected on aniguana. The second female was engorged 
on a box turtle and measured 14 by 9 by 5 mm. It died on the 
twenty-fifth day after dropping.

Larva (Tables XLUEX—LI).—The longevity of larve which hatched 
on July 14, 1908, was 95 days. This was the greatest longevity 
observed by us. Engorgement took place on a bovine as soon as 4 
days, the greatest number dropping from the fifth to seventh days. 
On a cold-blooded host (a tortoise) 10 days were required for en- 
gorgement. Ticks placed upon a bovine had all dropped on the 
ninth day, whereas upon a tortoise the last dropped upon the six- 
teenth day. An important point is here brought out in the fact that 
upon cold-blooded animals a much longer period is required for en- 
gorgement.
