L. intermedius. Lake Issik kul, Turkestan (Chaffanjon). Scales 

 broad, the broadest scales of true Leuciscus known to me; nucleus far 

 based of middle; apical circuii coarse; apical radii about seven; basal 

 radii about 2 to 5. 



Cyprinus. 



Cyprinus carpio. N. E. Mongolia (C. W. Campbell). Scale IS mm 

 long, 13 wide, parallel-sided, nucleus 91/2 nim from base; circuii very 

 fine; apical radii many but incomplete; basal radii exceedingly nume- 

 rous and close together, numbering over 70; no lateral radii. 



C. hollarii [Cyprinus X Carassius hybrid. Thetford, Norfolk 

 (Lord Walsingham). Scale shorter and broader, being about 12 mm 

 long and 11 broad; apical radii very many (about 26), wath very coarse 

 circuii between them; basal radii few, about seven; one or two radii, 

 below the apical, which may be called lateral. This shows the Cara.s- 

 sius characters very plainly, and also has the dusky-spotted Carassins 

 skin. However in Carassius (both vulgaris and aiirahis) the very coarse 

 apical circuii, except those close to the nucleus, are practically longi- 

 tudinal , meeting at an angle in the middle ; but in C. hollar ii they are 

 transverse, following Cyprinus. Carassius has very few basal radii, and 

 the apical radii are reduced to a few strong ones, the most persistent 

 being practically lateral. Carassius, therefore, approaches the alesti- 

 form type of scale, which is not at all the case with Cyprinus. 



C. priscus H. V. Mey. Miocene fossil. Unterkirchberg, near Ulm, 

 Württemberg. I could not see the base of the scale; the apical radii 

 were about four; circuii normal.
