SUPPLEMENTARY NOTE, PAGE 13 



Thyrsocles and Thyrsion (page 13). 



Just as these pages leave the press, Mr. Edward J. Porteous of 

 Lompoc has sent to Stanford University a large and perfect example 

 (Xo. 505: 22 1 /-> inches long) of the fish we have called THYRSOCLES 

 ESCHARION- This has the long jaws and crowded conical teeth of 

 THYRSION VELOX. The two species are in fact identical, and THYRSION 

 seems to be an exact synonym of THYRSOCLES. The name VELOX has page 

 priority and the species (if distinct from T. KRIEGERI) becomes THYR- 

 SOCLES VELOX. THYRSOCLES mentioned on page 7 was first associated with 

 a known species. 



THYRSOCLES, with the neural structures of SCOMBEROMORUS (oblit- 

 erated on plate IX,), is widely separated by the long jaws and close-set 

 conical teeth. 



ZAPH LEGES agrees with it in almost all regards, but has scales larger 

 than in any known mackerel. We have found no scales in THYRSOCLES, 

 but the two genera may prove identical. ZAPH LEGES certainly belongs 

 also to the SCOMBRID^E. 



PLECTRITES (page 28) ; an additional example shows the sides of the 

 jaws beset with molar teeth, as in LAGODON. PLECTRITES is probably a 

 synonym of RHYTHM IAS, the plectroid spine probably obliterated in the 

 type of R. STARRII. 



LOMPOCHITES (page 30) is not related to LOMPOQUIA. It is nearer 

 some of the CARANGID.E, perhaps to ELAGATIS. 



DIATOMGECA (page 40) certainly cannot belong to the PLEURONECTI- 

 IXE. No flounder has its peculiar arrangement of ribs and interhsemals. 

 We find as yet nothing like it, except perhaps in LAMPRIS. 



ECLIPES (page 41) belongs to the GADID.E or perhaps MERLUCCIID^E. 

 It cannot be a BROTULID.
