LIST F JAP A NESE FISHES— JOR DA N AND SNYDER. 747 



A. Ill, 5; CIS. Color bright yellow. Length, about fi inchen; deptli, 2; lliickiiess, 

 1 inch. It is perhaps most like Pseud olaln-us eMhinus. 



The name Labrus japonicus Schlegel, is preoccupied by this name of Houttuyn. 

 Schlegel's species may receive the new name of Chaerops azurio. It is a connuon 

 food fish of Southern Japan. 



14. LaBKUS BOOP8. 



This is Scomhropfi rJwilodipteroide.'i Bleeker, and may stand as Scombrops boops. 



Eyes very large, more than half an inch in diameter, thus taking up a very large 

 part of the head. Gill covers scaled. Lower jaw, the longer with fairly long and 

 sharp teeth. Dorsal tins, 2. D. V. 12; P. 14. V. 1, 5; A. 1 1 ; C. 22. 



15. Perc.\ fasciata. 



This seems to be Epinephehis .v^;^'»?/Vf.sc/a/tf.s {=su><itki =ocloci ixiiis) . The same 

 name Pern (fasciata was given still earlier by Forskal, to another species also found 

 in Japan, Epinepheliis fasciatus {^^=marg!nalis) tlie tyjie of the genus Ep'mepheJiis. 



16. Gasterosteus volitans Linnfeus. 



This is Pterois volitaus and refers to Pterols liinvldta. Schlegel. 



17. (tASTEROSTEUS .7APONICUS. 



This is Monocentris japonicus, a species of which Houttuyn justly says: "I have never 

 seen the equal of it." The same name Gasferosteiis japotdciis has been given by 

 Steindachner to a true stickleliack. The name of the latter thus i)re(X'(un)ied may be 

 clianged to that of Pygosteus steindachneri. 



18. Scomber .japonicus. 



This is the common mackerel of Japan, the Saba of the fisherman. We can not 

 separate it from Scomber colinsnl Europe. Houttuyn's name Sc(»nber japonicus, 1782, 

 has priority over Scomber co/ias (TUielin, 1788, or Scoriiher piieumatopltiiriis Delaroche, 

 1805. 



19. Scomber auratus. 



A little mackerel, 7 inches long, distinguished by its gilded color. D. IX, — ; fin- 

 lets, 5; P. 18; A. 6; V. 6. This must be the same as Scomber japonicus. 



20. Scomber trachcrus Linnanis. 



A common Japanese fish, close to Trachnrus tracJmriis, apparently the same. 



21. Cextrog aster puscescens. 



This in SI garrns fuscescens, from which Schlegel's Amphacanthns (dbopvncUttus and 

 aurantiacus do not seem to ))e different. 



Centrogasfer (= Slganus Forskal = Ampliacanthus Bloch) is a new genus defined by 

 the "strange growth of the ventral fins, which are like those in the Snottolf, named 

 liy Mr. C. Noseman, Ci/clogaster, grown together by a membrane which in this case 

 is supported by four sharp spines and six limber rays. ' ' The name is here misprinted 

 " Cantrogaster. " The confusion of the structure of the ventrals in S'iganus with that 

 found in Liparis shows that Houttuyn had no training in ichthyology. 



22. CeNTROGASTER AROiENTATUS. 



This is Leiogmtthits, or Eqwda michale, one of the conmionest of .lapanese fishes. 

 It may stand as Leiognathus argentatum. 



Entirely silvery, as if covered with silver plate. A large, round, l)rown s]>ot on the 

 back behind the head, and a black one in the dorsal fin. 1). VIII; A. 1 1, 12. Def)th, 

 I5; length, 3 to 4 inches. 



2,3. MULLUS .TAPONICUS. 



This is some species of Upeneus. It has been regarded as Midlus bensusi Schlegel, 

 but there is little certainty of this identification. D. VII-9. Caudal forked; mouth 

 toothless. Color more yellow than red. Length, 6 inches. A specimen from Tokyo 

 agrees with Houttuyn's ac(!Ount.
