One specimen, 56 mm. long, in splendid condition. 



Hab. Sarawak-river, near Kuching. 



Its place is between Acanthophthalmus pangia. H. B. 

 and A. Kuhlii, C. and V. 



It principally differs from A. pangia, H. B. by the place 

 of the ventral fins, the shortness of the barbels, the num- 

 ber of the rays in the dorsal and anal fin and by the 

 colour; from A. Kuhlii, C. and V., by the place of the 

 ventral fins and anal fin, the still shorter barbels , the 

 number of the dorsal and anal rays and the delineation 

 of the colors. 



This beautiful small fish has been presented to the Leyden 

 Museum by Mr. Shelford, Director of the Sarawak Museum. 

 I have named it A. Shelfordii to express my thanks for 

 this kind attention.
