132 GALIDIA AND ITS SPECIES. 



species distinct. Is. G. St. Hilaire however already described 

 the young of the elegans in the following terms "le jeune 

 age diffère de I'adulte par la couleur du dessus de son cou 

 et de ses épaules , region qui est d'un roussatre tiqueté de 

 fauve , et par la nuance moins foncée et moins vive du 

 rouge marron qui couvre le reste du corps. Les anneaux 

 noirs de la queue sont aussi moins marqués." Grandidier ^) 

 moreover remarks "le jeune et l'adulte ont la même colo- 

 ration ," and Bartlett *) states : "the colours of the young 

 are exactly the same as in the adult." 



Is. G. St. Hilaire had before him of the G. elegans se- 

 veral individuals and two skulls, of G. concolor a single 

 skin without skull , and of G. olivacea a single mutilated 

 skin with its skull. He accurately pointed out the diffe- 

 rences between the skulls of elegans and olivacea , and figured 

 the skull of the former. As nobody after him has spoken 

 of the skull of G. concolor , and supposed that olivacea has 

 a tail as long as in concolor, olivacea might just be 

 the young of concolor, or the contrary might be the case. 

 So , there are three questions to solve , viz : 



I''. If there are differences between the skull of concolor 

 and the skulls of the other species. 



2°. How long the tail of olivacea is. 



3*^. How many species of Galidia we must admit. 



Up to last year the only species of the genus Galidia 

 represented in our collection was G. elegans; we possessed 

 three specimens and three skulls , two adult ones labelled 

 "Bernier 1834" and therefore originating from the same 

 collection to which belonged the types of Is. G. St. Hi- 

 laire's G. elegans ; the third specimen , a very young one , 

 was purchased in 1875 of Mr. Frank in London and very 

 likely belonged to the collection of Mammals and Birds

2) P. Z. S. L. 1875, p. 64. He had before liira an about half-grown 

 young one.
