Leaving Agua Verde on April 2 at 1 1 : 30, we reached Carmen Island, 

 celebrated for its salt deposits, at 3: 30, anchoring off the salt works. Here, 

 as at other islands visited, the party made the most of the time afforded. 

 The fishing operations yielded many food and other fishes. For the benefit 

 of the botanist, the manager of the salt works provided horses for a ride to 

 Ballandra Bay on the west side of the Island. Passing down a valley lead-

 of food fishes of several species, among them being "cabrilla piritita" 

 (Mycteroperca partialis) and "mojarra dorada" (Gnathanodon speciosvs). 

 Among the mammals obtained were two new species of mice (Pcrognathus 

 sjrinatus occultus) and (Peromyscus ercmicus earmeni). The salt deposit 

 of Carmen Island is a notable one. It is in reality, a lake of snow-white 

 salt nearly two miles long and a mile wide. The surface salt is dissolved 

 during the annual rainy season and after re-crystallizing forms new supplies. 

 The deposit appears to be inexhaustible and only about one-tenth of the lake
