Osgood Unrecognized and Misapplied Names. 47 



It represents a form which seems worthy of recognition though some 

 what intermediate in characters between niger and rufiventer. It is slightly 

 larger than rufirenter, but has the same ferruginous general coloration, 

 while the nose and ears are white but less extensively so than in niger. 

 Specimens showing these characters are in the Biological Survey Collection 

 from Pontchatoula and Rayne in the coast region of Louisiana, and from 

 Bay St. Louis, Mississippi. 



My own notes of importance on the type specimen are as follows : 



" It is a richly colored specimen and agrees most nearly with a British 

 Museum specimen from Louisiana received from Audubon. The top of 

 the head has black predominating though there is considerable ochraceous. 

 The forehead and nose are bare of hair except a little patch on the nose 

 which is soiled white and from this I should judge that the nose was ex 

 tensively whitish. The ears are ochraceous, of a paler shade than the sur 

 rounding parts, even inclining to whitishin places. Length, nose to base of 

 tail over body, 345 mm.; tail vertebrae, 280; hind foot, 74.1." The speci 

 men is No. 204 and is labeled and entered in the British Museum register 

 as " Sciurus texianus Bachm. Texas." 



The specimen in the Paris Museum is No. 452 and labeled " Sciurus 

 texianus (Back.) Type. M. Price. Texas." On the bottom of the wooden 

 stand on which it is mounted is some illegible writing and the following: 

 " du Texas. Sciurus texianus (Bach.). Bachman probl.' le type." The 

 pelage is rather worn, the upperparts are chiefly grayish, and the under- 

 parts are practically white. It measures : Head and body, 300 mm.; tail 

 vertebrae, 280 ; hind foot, 70. This specimen should perhaps be re 

 ferred to S. n. limitis, but it is not improbable that it is an example of 

 S. n. neglectus wrongly attributed to Texas. Its completely white under- 

 parts are absolutely incompatible with Bachman's description oftexianus, 

 in which these parts are said to be deep yellow. Therefore, it can not 

 justifiably be taken as the type of texianus. 



The locality " Texas" assigned to the British Museum specimen is doubt 

 less erroneous since Douglas did not collect in that State or within the 

 range of this squirrel. The only recently collected specimens agreeing 

 with it are from the coast of Louisiana and Mississippi, representing a 

 hitherto unrecognized form, which, therefore, takes the name Sciurus niger 

 texianus.

It appears necessary to use the above name for the beaver of the North 

 west coast lately called pacificus. The original description is limited but 

 its basis is readily determinable. Three specimens are mentioned, collected 

 by Robert Brown on the Northwest coast of America and doubtless still 

 preserved in the British Museum. The exact locality is not stated but it
