1S87.] NOMLNCLATUIUC Of INDIAN MAMMALS. 621 



In the twelftli edition of the ' Systema Naturse,' vol. i. p. 36, 

 Simia silenus is described thus: — 'SS'. caudata barbata nigra, barba 

 nigra prolixa. Habitat in Egypto. Species obscuriar, ignotis. 

 Pedum unguibus, aliisque phirimis attribuiis." Neither the colour 

 of the beard nor tiie locality agrees with the Malabar Monkey, 



Two references are given by Linnajus thus : — 



" Simia Callitriches magnitudine Cynocephalorum. Alp. £eo-vut. 

 242 ? •> f 1 P. ^' 



" Cercopithecus barbatus niger, caesarie prolixa faciem cino-ente 

 Briss. Quad. 209." 



Brisson's account was, however, taken from Prosper Alpinus's 

 work, to which the first reference in Linnaeus applied. It is thus 

 manifest that the 5'. silenvs of Linnaeus is ibunded solely on 

 P. Alpinus's description. His work is entitled " Prosp. Alpini Hist. 

 iEgypti naturalis pars prima. Lngduni Batavorum, mdccxxxv." 

 At p. 242 are several descriptions of Monkeys, but bearded species 

 are only described towards the bottom of the page. The work is 

 rare (the only copy I have seen is in the British Museum), so I 

 append a somewhat lengthy extract. 



Tertius est ex iis qui vulgo Monichi vocantur caudati, & *** Jldc. 

 barbati : ex Ethiopiae locis conterminis in iEgyptum deducuntur, * 'b- ^^- u'"". 

 suntque admodum cicures, & mundi, non tamen eo iugenii acuminei ^' 

 ut alii Cynocephali donati sunt. At ut feles naturain ingenii 

 habent, atque hsec de Simiis Cynocephalis a facie canina vocatis 

 sufficiant. Sequuutur has Simioe caudatae & barbatae, quas Calli- 

 triches Aristoteles vocavit, qua3 prioribus admodum dissimiles cer- 

 nuntur. Quaedam maximorum Canum magnitudinem habent, & 

 quaedam mediocris sunt magnitudinis. Raro hfe Simite bipedes 

 incedunt, sed quadripedes brutorum modo. Habent alias differ- 

 entias quibus interstinguuntur ; etenim aliquae ex iis toto corpore 

 figura ad leones accedentes, orinitasque jubas veluti leones habere 

 videntur, sed pilis nigris pendulas. If Hie simius in pectore «r nje 

 crassior apparet, & circa ilia subtilior, ut leones. Caudam latam tab. xx. num. 

 pihs longis, prolixisque cubitalem, & ampliorem habet : fades vero 2. 

 ad leoninam quadantenus inclinat, ore & dentibus itidem proximis. 

 Barba ex mento pendet longa, lata, nigris pilis obsita. Aures 

 humanis longiores cernuntur, totaque i'acies nigerrimo splendet 

 colore. Hie Simius baud injuria a nobis Callitriches leonino corpore 

 dictus est." 



With regard to the figures, tab. xx. fig. 3 represents an animal 

 with a thm beard, below the chin alone, and with a rather long 

 tail ; tab. xx. fig. 2 shows a Monkey drawn so as to resemble a 

 Lion as much as possible. Neither figure has any resemblance to 

 the Malabar Monkey. 



It should, however, be observed that a note of interrogation 

 occurs after the number of the page in Linnajus's reference, and I 

 have no doubt that the animal to whicii it was intended to refer was 

 one described by Prosper Alpinus on p. 244 in the followino- 

 terms ; — °
