BULLETIN FLORIDA MUSEUM NATURAL HISTORY VOL. 46(4) Table 3. Morphometric and meristic counts for Synodontis dhonti. All morphometrics given in percent of base measurement. SL = Standard length, HL = Head length, LMB = Lateral mandibular barbel, MMB = Medial mandibu- lar barbel, HPL = Humeral process length, HPD = humeral process depth, CPL = Caudal peduncle length, CPD = Caudal peduncle depth.
