Family CEPHALAGANTHIDJE. 



166. Cephalacanthus volitans (L). II. XshoirMJi^'apo (J, swallow-fish. 

 Apostolides 15 (Dadi/lopterus volitans), yihoo^M'til^apo. Aposto- 



lides identifies this with the yMy./.ij'= of Aristotle. But may it not 

 be the sea yjhd(u.> spoken of by Aristotle 535b 27 ? He says : " The 

 zr/vrs' when they rush ah)ng, re-;ting upon the water (which people 

 call living), make a whizzing sound, and the sea swallows («? OaXdiz- 

 Ttat yjhDo,';^') do the same, for these fly in the air not touching the 

 water." 



Cuvier identifies this sea swallow with Dad. volitans. Compare, 

 however, Trigla hirundo, still called yiX'.i^oMi., the swallow. 



Of the r.iy/.y.o:, cuckoo, Aristitle (oiJSa 15 and 535b 20) says : " It 

 makes a sound like the cuckoo, whence it gets it name." The /.i'ia- 

 yjjys^ are both pelagic and littoral (alternately). Vide Plin. Hir- 

 undo, 9, 82 and 32, 149. Athen. vii, 84. 



There is nothing in any reference that lean find to show that the 

 xoxy.u^ was a fli/iiifj fish. According to Apostolides 13 Uranoscopus 

 scaber is called y.oJ'yy.d?, M. G. for cuckoo. May not this be y.oy.xu^'i
