meridional la canlnuB BONAPARTE , then on the grounds of ioo­geographical considerations the latter may live only la the Balkan Penineula as a wide-spread form in this region. Literature indicates the greatest difference between the two subspecies the number of scales on the lateral line. The number of scales of Barbus meridionalis caninus BONAPARTE found by CANESTRIKI /1874/ when examining Italian specimens was 48-50 and that of Barbue meridionalis petényi HECKEL «as 55-60 found by HECKEL /1858/. If thia were trus t the two forms could very easily be segregated by a simple counting of the number of scales only . But a survey of the relevant literature reveale that the varioue authors gave scale numbers very different from those of the original descriptions. Our authore quoted below found the following values in Barbue meridionalis BONAPARTE. STEIN DACHNER /1883/ exsained 9 specimens from the Lake Skutari sad found the following numbers of scales: 1 spec, had 46, 3 spec. 47, 1 spec. 49, 3 spec. 50, and 1 spec, 52. Mean 48.7. He commented on these ae follows : „Keines Erachtens glaube ich aus der Schuppenzahl der Barbus exemplare aus dem Riekaflusse und des Sees von Scutari annehmen su dürfen, das s Barbus meridionalis Rleeo und Barbas petényi Heckel nur als Abarten ei»er und dersel­ben Staamart su betrachten seien, welche Ansicht Jeittelea bereits in Jahre /1862/ ausgesprochen hat." KARAMAN /1924/ examined 7 specimené from Macedonia and found the following numbers of scales: 1 spec. 49» 1 spec. 51, 2 spec. 52, 2 spec. 53, 1 spec. 55. Mean 52,1. VTBCISUERRA /1930/ reported two epecimens from the Lake Ochrid to have 51 scales. OLIVA /1950/ examined 2 specimens from the Lake Pre apa. having 50 and 52 scales, respectively. Nor do the scale numbers of Barbus meridionalla pe­ tényi HECKEL epecimens correspond with those of HECKEL' s \ description. In this reepect the data of BANARBSCU /1957/ are very Important. This author examined 421 specimené from
