TURRIALBA AND PERALTA 267 



ably occur in Costa Rica, Odontocoslus truei, costaricensis 

 and nemoralis, and Mazama sartori. Miller spells the first 

 of these generic names Odocoileus and gives tema as the 

 specific name of the Mazama. Odocoileus, which includes 

 the Virginia deer of the United States, has branched or un- 

 branched antlers (but on the male only) and usually a long 

 tail and a metatarsal gland. 0. truei has (in its summer coat) 

 the upper parts light chestnut or tawny, the tail tawny 

 above, the height at the shoulders 27 to 29 inches. 0. 

 costaricensis is larger than 0. truei, is mixed black and buff 

 above, has the tail cinnamon above and a total length of 

 56 inches. The upper parts of 0. nemoralis are yellowish- 

 brown and gray, the tail dusky above, the height at the 

 shoulder 27^^ inches (Lydekker). 



Mazama has simple unbranched horns which are directed 

 backward, a short tail, the hair on the forehead forming a 

 tuft, but no metatarsal gland. M. tema (or sartori) has the 

 upper parts of the body and of the tail brownish-red, the 

 height at the shoulder 2o3^ inches. It is one of those deer 

 known as brockets. 



Between four and five that afternoon I saw a few toucans 

 by the Chiriqui, both perching and flying. When flying, 

 a toucan is elongated and bent down in front and so at the 

 opposite extreme from a parrakeet in flight, the latter appear- 

 ing very short and "sawed off" in front. 



The green-and-golden-eyed, blood-sucking flies, Chrysops 

 tanycerus, were here in numbers to-day. This genus of the 

 horse-fly family is widely distributed over the earth and per- 

 secutes man and other mammals wherever it occurs. 



This day being Good Friday, not a train or an engine 

 moved in either direction on the railroad and a construction 

 train which arrived at Peralta on Thursday evening waited 

 until Saturday before going on. Such was the custom of the 

 country rather than the wishes of the railroad management.
