rather ])roa(l margins, color adjoining almost blackish but fading out 

 to brownish ground-color soon, though on caudal distally more darker 

 than on other fins. Pectoral mottled with brownish, becoming dis-

TypeNo. 2,349, W. I. A.P. Baram, Borneo. 1897. Mr. Alfred C. 

 Harrison, Jr., and Dr. H. M. Hiller. Also paratypes No. 2,381, 

 W. I. A. P., with same data, and No. 2,509, W. I. A. P., from the mouth 

 of the Baram river, collected by Dr. W. H. Furness in 1898. 



This species is closely related to Leptosiinanccia asterohlepa (Richard- 

 son),^^ but differs at once in coloration, the edges of all the fins in that 

 species being blackish, while in Leptosynanceia greemnani they are 

 margined with whitish on the rayed dorsals and anal, and caudal. 

 Bleeker's figure'* shows a more n\arbled appearance, but the edges of 

 these fins are also dark. Further, the dark and pale markings on the 

 trunk are exactly negative to L. greenmani. 



(Named for Dr. ^I. J. Greenman, Director of the Wistar Institute 

 of Anatomy in Philadelphia.)
