It is useless to attempt a division of this genus, for there is .such a gradual 

 chain of chunicters between the two extremes of form {riifii>^ and cr'imdis), 



that they even seem almost one si)ecies, 

 when the numerous intermediate forms, 

 shading so insensibly into each other, are 

 considered. However, as this view would 

 be rather extreme, in view of the really 

 great dilference of form between the speines 

 mentioned, we may consider the following 

 as good sjjeeies, severai of them with one 

 or more varieties: rn/ns, with lonyiniuihi. 

 and /oiii/irosfn'x as varieties, the fornuu- 

 scarcely ap[)reeia.bly dilferent, the latter 

 ranking as a permanent race ; orcUcttnx, ri- 

 nfiriia, ciirviroHtris, tht; latter witli one well- 

 marked variety, pn/iiicn' ; mlivini.-i, with 

 most probably Invntd as a well-markeil 

 variety, and rrinsn/l.'i. 

 Tlie seasonal dif1eren<;es in the i)himage often make it ditheult to deter- 

 mine these several forms ; but if the following iiicts are borne in mind, the
