with mainly in the "tortora" fields which occupy the more shallow- 

 parts of the lake. The lake is flanked on the eastern and western 

 sides by high hills that rise quite abruptly from its shores, which are 

 scantily covered with short grasses, cacti, and other coarse spiny 

 plants. There are quite extensive plains at both the northern and 

 southern ends of the lake. Shrubs and low trees occur in some of 

 the ravines and on the island of Titicaca, but they are confined 

 mostly to the southern end of the lake. 



Mr. Garman has been able to add interesting field-notes respecting 

 most of the species, which are given in quotation-marks, and are 

 taken mainly from his notedjooks. Several of the species arc left 

 undetermined, some of which may prove to be new ; but the only 

 ones I have ventured to describe as such are a Gallinule — a large 

 and strongly marked species — and an Ibis. 



MAMMALS. 



1. Conepatus nasutus (Bf.nnett) Guay. Three specimens were 

 obtained, — a female, and two young ones about half grown. 



2. Auchenia Glama (Linn.) Desm. " The Llama is in this region the 

 beast of burden, but is never ridden. A hundred pounds is considered a 

 sufficient load. Should the animal be overloaded he refuses to go, and is to 

 be induced to move on only by lessening the amount of his load. A load 

 that he is willing to start with is generally one that he can carry the entire 

 day. "When travelling where there is a trail the herd march in single 

 file, the driver or drivers walking in front or behind, and urging them along 

 by an oft-repeated hissing, or l sJi — sh — sh.' They are never beaten and 

 seldom shouted at. The males are commonly used as the carriers, or " car- 

 gadores." To improve the wool of the Llama, which is inferior to that of 

 the Alpaca, the natives are in the habit of crossing the two races." 



The collection embraces one skeleton and a skin. 



". Auchenia Pacos (Linn.) Tseh. ''The Alpacas are raised for their 

 wool, and are not used as beasts of burden. As the coat is not shed each 

 year, if not sheared for several seasons the wool grows to be a foot to 

 eighteen inches in length. A year after shearing it is less than six inches. 

 The entire fleece is never taken off. great ragged-looking bunches being left 

 on the thorax and about the shoulders, 'to protect the animals.' 



"The Alpaeas and Llamas form the chief wealth of the Indian. Knowing 

 his herd to be a source of continual profit, he is loath to part with any of it 

 for money, which ' must be buried in the ground.' Hence it was difficult to
