we had learned to expect in local species in each well-marked 
division of the islands were wanting entirely, and our trips inland 
afterwards failed to discover them. Among these genera con- 
spicuous for their absence were two of the three commonly dis- 
tributed genera of hornbills, three of the four genera of wood- 
peckers, and several genera of kingfishers and cuckoos. Among 
the new birds brought in was a little parrot, Loriculus, closely 
resembling the Luzon species, but sharply distinct from it; anda 
new species of the genus of small black hornbills (Penelopides). 
We had found the five species of this genus already collected with 
the male always white-headed and the female with the head 
black like the body ; but our Mindoro species was white-headed 
in both male and female, the only distinction in color between 
the sexes being that the male had the bare skin about the face 
flesh white, while the female had the same parts livid blue. A 
little way back among the hills another crow was found, much 
smaller than the common crow and with a shorter tail, and 
flight resembling that of the parrots. This little crow had a. 
curious flat voice, reminding one of the croaking of frogs and 
also of the notes of the katydid. On dissection it proved to be 
distinct in food from the common species, being limited to fruit. 
We were soon visited by several collectors of land and tree 
shells,—the same ones who by sending quantities of their collec- 
tions to Manila have made the beautiful Mindoro tree snails well 
known in Europe. The Mindoro species are apparently more 
peculiar than those of Paraguay, there being several sections of 
genera limited to this island. 
The ¢amarou were said not to be found within less than two 
days’ journey of Calapan; and as the rainy season was coming 
on, we hastened our preparations for our visit to the interior. 
That we might run the greater chance of getting the object of our 
search we decided to divide our party; and Bourns and Wor- 
cester set out by native boat a day’s journey down the coast to 
the south, and then inland in their search for the lake Naujan, 
which was said to be a famous haunt for these animals. They 
found the lake to be of considerable size, but shallow and with 
great mud-flats, and much of it grown up with water plants and
