Fam. 85. Mullidae. Red mullets, sHghtly compressed, covered with 

 large thin scales which may be ctenoid ; two long erectile barbules on the 

 hyoid ; two short dorsals remote from each other ; pelvic s with 1 

 spine and 5 rays ; branchiostegals 4 ; mainly tropical. Midlus L.,

 compressed ; mouth protractile ; minute teeth on jaws and vomer ; Medi- 

 terranean, Atlantic. Capros, Antigonia. 



Fam. 87. Chaetodontidae, sometimes separated as a distinct tribe 

 and divided into families, may also be placed here ; the soft part of the 

 unpaired fins and sometimes the spinous part are covered with small 

 scales. The body is compressed and elevated and covered with scales 

 either ctenoid or smooth ; the limits of the gi'oup are vmcertain ; it includes 

 forms showing analogies with the Carangidae on the one hand, and with 

 the Percoids on the other, and there are featmres of specialisation which 

 lead towards the Plectognathi. The majority are from tropical seas, and 

 abound chiefly in the neighboiu'hood of coral reefs. The beauty and 

 singularity of colouring of some of the genera, e.g. Chaetodon, Heniochus, 

 Holacanthtts are remarkable.
