BATRACIIIANS AM) FISHES FROM UGAXUA oOo 



The large series of specimens from British East Africa and the 

 Congo which has lately passed througli my hands compels me to 

 adhere to my former view that Gray's Ch. laevigatas should not 

 be regarded as representing more than a race of Ch. senegalensis, 

 notwithstanding Prof. Tornier's emphatic assertion that it has 

 « mit Ch. senegalensis gar nichts zu thun » . The supposed 

 principal distinctive points, viz. the absence of conical vertebral 

 tubercles forming a feeble serration on the anterior part of the 

 back, the finer granules of the body, the posteriorly less defined 

 casque , and the extent of the white ventral streak on three 

 series of granules, are all inconstant. I may mention that the 

 actual types of Gray's species as well as a female from Uganda 

 (Coll. Ansorge) have the vertebral serration as well marked as 

 in some West african specimens, representing the true Ch. sene- 

 galensis; that the above mentioned female from Uganda has the 

 granules on the body coarser if anything than in a male of the 

 same size from Nigeria (Coll. Dalton); that the casque is often 

 as distinctly separated from the dorsal keel in East as in West 

 African specimens; that East African specimens with only the single 

 middle ventral series of granules white are not unfrequent, this 

 being the case in the types of Ch. laevigatas as well as in the 

 Sesse specimens. Prof. Tornier adds that Ch. laevigatus is one 

 of the smaller species of the genus giving 178 millim. as the 

 maximum total length; but a female in the present collection 

 measures !210.
