Rh. minimus^. — The type, an immature but full-growu 

 male (in alcohol), preserved in the Stuttgart Museum^ is

 Rh. hipposiderus.

Results. — Rh. minimus is undoubtedly referable to Rh. 

 hipposiderus as a sjjecies. It has the decisive characters 

 of this latter, above all : (1) the comparatively well- 

 developed upper jj-, placed entirely in the tooth -row; 

 (2) the long and very narrow sella, with the lateral margins 

 convergent towards the summit, the summit itself sharplv 

 pointed; (3) the 5th metacarpal shorter than or, at most, 

 equal to the 4th. But it is decidedly smaller and, especiallv, 

 shorter-taikd. There is in the Bi'itish Museum a speci- 

 men from Sennar ( ? ad., in alcohol, no. 47. 5, 27. 48) 

 exactly like the type of Rh. minimus. This form therefore, 

 probably, should be kept distinct as a small short-tailed race 

 of Rh. hipposiderus.
