over 6 or 8 feet deep. At La Palma is a rich growth of cat- 

 tails and tules. The bottom, a short distance from shore, is 

 muddy. Our collection was made along shore, in and about the 

 tules, and some distance out where the water was not deep. 

 There is considerable fishing done here for the market. The 

 cat-fishes Ameiurus dugesii are known as Bagre. Xystrosus pop- 

 oche and Falcula ciiapala are Sardinia. Algansea rubescens is La 

 Poache. The large Chirostoma' are Blancas, and the small Chir- 

 ostoma and the various species of Pxciliidce are known as Mojarra. 

 The fishes caught here are marketed largely in Ocotlan. 



At Celaya a small collection of fishes was made in a small 

 stream which flows by the depot. In this stream was consider- 

 able vegetation. 



The Rio Lerma at Acambaro is a clear stream not over 4 feet 

 deep, flowing over a sandy bottom. It contained but few fishes 

 at this place. A large irrigating ditch well filled with aquatic 

 vegetation yielded a good number of Pceciliidce. 



Lago de Quitzeo is a large shallow lake without any outlet. 

 At Huingo, where our collection was made, the lake was not 

 over 2 feet deep as much as one-eighth of a mile from the shore. 

 At one-fourth of a mile it is less than 6 feet deep. There are a 

 number of hot springs along the shore west of Huingo, and near 

 the depot a small stream fed by a warm spring flows into the 

 lake. This stream was alive with Pceciliida. Between the lake 

 and the city of Huingo a large amount of salt is gotten each year, 

 and so the lake is known as a salt lake, though its waters may 

 perhaps be but little if any more saline than are the other lakes 

 in this region which have no outlets. The small Pivciliida are 

 known here as Charral. 



Lago de Patzcuaro is a beautiful sheet of water some 10 

 miles long by 2 to 4 miles wide. It is surrounded on all 

 sides by high mountains, and is -perhaps the most beautiful and 

 picturesque lake in the Lerma Basin. Its shores near the city of 

 Patzcuaro are fringed with a rich growth of tules and other 

 aquatic plants. About 3 miles from the landing is an island, 

 and between it and the shore the lake does not exceed a depth 

 of 30 feet; beyond the island it is reported to be much 

 deeper. A great deal of commercial fishing is done here. The 

 larger fishes, Pescados Blancas, are marketed at Patzcuaro and 

 Morelia. A few are sent to Uruapan and neighboring towns. 

 The small fishps of all species are dried in the sun and marketed 

 in that condition. The fishes are caught in long seines. Lago
