454 A new Generic Name/or an Orectolobid Shark. 



E. majori there are representatives of two species, the original 

 E. majori from Ambohimitombo, Tanala Country, Central 

 Betsileo, and a second from Ampitambe", N.E. Betsileo. 

 Adopting the specific name used provisionally in Madagascar 

 by Dr. Major, I propose to name the new form 



Eliurus penicillatus, sp. n. 



Size about as in E. majori; colour-characters as in 

 E. tanala, Major, i.e. with the digits, both fore and hind, the 

 sides of the hands and feet, and the end of the tail white, 

 these, parts being mostly brown in E. majori; there is some 

 variation, however, in these respects, the main distinction 

 b itween the species being in the skulls. 



Brain-case of E. penicillatus long, oval, tapering forward, 

 of E. majori comparatively short and broad. Palatal foramina 

 of penicillatus widely open, their combined width equal to or 

 more than half their length ; of majori narrow and contracted, 

 their width much less than half their length. Molars of 

 penicillatus much smaller, both shorter and narrower, than 

 those of majori. 



Dimensions of the type (measured in skin) : — 



Head and body 147 mm.; tail 164; hind foot 31 ; ear 21. 



Skull: greatest length 36; basilar length 27'4; greatest 

 breadth 17*4; nasals, length 145 ; interorbital breadth 5; 

 palatilar length 15 ; diastema 10 ; palatal foramina 6"2 x 3*1 ; 

 length of upper molar series 59. 



JLib. Ampitambe, N.E. Betsileo, Madagascar. 



Type. Adult female. B.M. no. 97. 9. 1. 149. Original 

 number 602. Collected 20th July, 1895, by Dr. 0. I. 

 Forsyth Major. 



LIX. — A neiv Generic Name for an Orectolobid Shark. 

 By C. Tate Regan, M.A. 



In 1906 (Proc. "R. Soc. Queensland, xx. p. 27) Mr. Douglas 

 Ogilby proposed the generic name Brachcelurus for Giinther's 

 Chiloscy Ilium modestum. In a more recent paper (Proc. R. 

 Soc. Queensland, xxi. 1907, p. 3) he diagnosed the genus, 

 but transferred the name to B. colcloughi, described as a new 

 species, and on the next page made C. modestum the type of 

 another genus, Cirriscyllium. As B. colcloughi does not 

 appear to be congeneric with B. modestus, it becomes neces- 

 sary to propose a new generic name for the former species ; 

 the two genera, with their synonyms, are : —
