Etude sur les Algues Parasites des Paresseux, — Mme. A.

This is a very interesting account of a symbiotic alga inhab- 

 iting the hairs of the Sloths and giving to their fur its frequent 

 green coloring. As these animals live in the warm, moist, trop- 

 ical forests, the algse multiply immensely in the spongy tissue of 

 the hairs, crowding the cells and penetrating even to the horny 

 centres. After giving a resume of the work and methods of in- 

 vestigation, the author describes two new genera and three new 

 species : Trichophilus Welckeri^ Cyanoderma Bradypodis and C, 

 Choloepodis.
