1S87.] NOMtNCLATURE OF INDIAN MAMMALS. 621 



In the twelfth edition of the ' Systema Naturae,' vol. i. p. 36, 

 Simla silenus is described thus: — " S. caudata barbata nigra, barba 

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

 Pedum U7iguibus, aliisque plurimis attributis." Neither the colour 

 of the beard nor the locality agrees with the Malabar Monkey. 



Two references are given by Linnaeus thus : — 



" Simla CaUitriches magnitudine Cynocephalorum. Alp. eegvpt. 

 242? 



" Cercopitheeus barbatus niger, csesarie prolixa faciem cingente. 

 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 tliat the 5. silenus of Linnaeus is ibunded solely on 

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

 ^gypti naturalis pars prima. Lugduni 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, & *** ^'ide 

 barbati : ex Ethiopise locis conterininis in ^gyptum deducuntur, * '''• ^^- "'""• 

 suntque admodum cicures, & mundi, non taraen eo ingenii acumine, 

 ut alii Cynocephali donati sunt. At ut feles naturam ingenii 

 habent, atque hsec de Simiis Cynocephalis a facie canina vocatis 

 sufficiant. Sequuutur has Simiae caudatae & barbatse, quas Calii- 

 triches Aristoteles vocavit, quas prioribus admodum dissimiles cer- 

 nuntur. Quaedam maximorum Canum magnitudinem habent, & 

 quaedam mediocris sunt magnitudinis. Raro hae Simiae bipedes 

 incedunt, sed quadripedes brutorum modo. Habent alias differ- 

 entias quibus interstinguuntur ; etenim aliquae ex iis toto corpore 

 figura ad leones accedentes, crinitasque juhas veluti leones habere 

 videntur, sed pihs nigris pendulas. 5[ Hie simius in pectore •[ ruie 

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

 pilis longis, prohxisque cubitalem, & ampliorem habet : facies vero 

 ad leoninam quadantenus inclinat, ore & dentibus itidem proximis. 

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

 humanis longiores cernuntur, totaque facies 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 thin 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 Linnaeus's reference, and I 

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

 one described by Prosper Alpinus on p. 244 in the following 

 terms ; — 



" Quaedam Simiae ex Callitrichis visuntur magnitudine magnorum
