42 Dr. A. Wasjner on some new Brazilian Mammalia. 



"CJ 



it the name of Edwardsia vestita, with the following diagnosis^ 

 referring for a full description to my former account of it. 



4. Edwardsia vestita. Apice piano, tentaculis biseriatis, exterioribus 

 32 longioribus; parte media cylindrica ; epidermide crassa, trans- 

 lucida. Long. 3 — 4 unc. 



III. In the 8th volume of the ^ Annals ' are some interesting 

 papers by the Eev. D. Landsborough and Mr. Hassall on the 

 Phosphorescence of Zoophytes. Before however we can assert the 

 general phosphorescence of that class of animals, we must have 

 many more observations than can be fui'nished by an examination 

 of British species only. The general fact has long been known 

 to British naturalists, though but little has been written about it, 

 more precise observations than we have yet on record being re- 

 quired. These we must still attend. In the Medusae and Tu- 

 nicata the light appears to be derived from special organs (see 

 Wagner's observations on this subject), and in polypes will pro- 

 bably be found to proceed from similar points.

VI. — Characters of several new Species of Brazilian Mammalia. 

 By Dr. A. Wagner of Munich*. 



Most of the animals of which the following are the diagnoses 

 are contained in the collection at Vienna ; those from Munich have 

 Mils. Monac. affixed to them, and there is one new species for the 

 use of which I am indebted to the kindness of Dr. Riippell. With 

 respect to the names of the species, I have adhered to the rule laid 

 down in Schreber's work, to leave unaltered the names of species 

 as given in the collections if found by me to be new, and even 

 when I have arranged the species under a different genus. 



Callithrix brunnea, Natt. C. saturate fusca, taenia frontali lata mani- 



busque nigris ; vellere breviori, adpresso, stricto. — Altitude a ver- 



tice ad anum 12|", cauda 17|". 

 Callithrix caligata, Natt. C. dilute fuscescens, pilis dorsi nigro flavo- 



que annulatis, gastrseo genisque cupreo-rufis, manibus sincipiteque 



nigris. — Altitude 12j'^ cauda 14|-". 



Borba et Rio Solimoens. 

 Chrysothrix entomophaga, D'Orb.f C. serina, supra nigro-mixta, ca- 

 pita supra aterrime, antibrachiis manibusque splendide auree-fulvis. 



—Altitude 11", cauda 14f' . 



Rio Mamere. 

 Hapale chrysoleucos, Natt. H. albida, manibus caudaque splendide 



rutilo-fulvis, auriculis albe-penicillatis. — Altitude 9", cauda 12|-". 



Berba. 



* From Wiegmann's " Avchiv," vol. viii. Part 6. 



t Although this species has been figured by D'Orbigny under the name 

 of Callithrix entomophaga, it has not yet been described.
