PRINTED IN GERMANY PREFACE. THE present volume, which succeeds Volume I. after a comparatively short interval, contains the completion of the account of the Suborder Ostariophysi. Of the Families belonging to this Suborder, the Characinide are described in Volume I., which also includes three genera of Cyprinide. The present volume thus contains the greater part of the Cyprinide and the whole of the Siluride. Much of the material on which the Catalogue is based has been presented to the Museum. ‘The lists given under the respective species contain some record of the way in which the specimens have been acquired, and imply an acknowledgment of the fact that the preparation of the Catalogue has been largely facilitated by public and private generosity, SIDNEY F. HARMER, Keeper of Zoology. Brizish Museum (Nsrurat History), Lonpon. December, 1910. — oo j er » 1 > ' ely : i teeny wnt , 4 ¢. = ida piel voted, OEE mail ) Sancp ie Ess = 2 iit OS? i) ey ' ‘ ; i ie Gears | 1) $4 3 Lon 2 7 alot ) aay 1¢ ‘aot ory —-» INTRODUCTION. THE first volume of this Catalogue contained the descriptions of 302 species and the enumeration of 3380 specimens. In this second volume, which deals with the bulk of the Cyprinide and the whole of the Siluride, the number of species and specimens amounts to 428 and 4434 respectively. The enormous increase in the number of species of Barbus, mostly discovered during the last decade, shows how greatly an exploration of the fresh-waters of Africa was needed. That our knowledge of these fishes, from the purely systematic standpoint, is still far from complete is shown by a large collection brought home from Angola by Dr. Ansorge since the present volume was set up in type, as it contains examples of as many as nine new species of Barbus to be added to the 185 here defined.

Europe, Asia, Africa. A. Bb. C. Scales of three species of Burbus. A. B. bynnt; B. B. pleurogramma ; C. B. perince. The structure of the scales varies considerably according to the species. In #. bynni and its allies the exposed surface is striated by numerous longitudinal, scarcely radiating, straight or slightly wavy canals, visible to the naked eye or with the aid of a magnifier of low power f, whilst the centre is more or less finely rugose. In B. fluviatilis and other species with small scales the striations are likewise numerous, but they radiate fan-like from the centre ; whilst in B. perince, and other small species with large scales, they are reduced to from two to five, radiating from the centre, the scales appearing smooth, but for the fine concentric striation.(growth-lines) which is present on the scales of all Cyprinids. The three principal types of scales are here figured, as the character has been used in the arrangement of the species. * The last ray is ‘bifid and often cleft to the base, so as to appear as two; even when thus completely divided it is supported by a single bone, and is therefore reckoned as one. Tt Except in spécimengs that have had the scales decalcified by preservation in formol. eo BARBUS. Synopsis of the Species. I.

Different groupings could be adopted according to the weight attached to the size of the scales, the structure of the mouth, the position of the dorsal fin, &c. The arrangement here followed is that which appears to the author to lead most readily to correct identification of specimens. 26 Bou I/II Se. Se.
