398 LABRICHTHYS AND PSEUDOLABRUS — GILL. 



Dr. Giiuther, in "An Introduction to the Study of Fishes" (1880), and 

 in the later German translation, " Handbuch der Ichthyologie" (1886), 

 retained the same arrangement of the Labrids as that proposed in 18G2, 

 adding no other genera, and supp'ressiug or ignoring one [Callyodontich- 

 thys).* But there is much more to be taken into account. 



In 1SG4, Professor Kner described a fish from the Samoa Islands with 

 both lips having a fimbriated margin under the new generic and spe- 

 cific terms Thysanocheilus ornatusA 



In 1866, Drs. Kner and Steindachner made known another fish from 

 the Samoa Islands, also having both lips produced and with a dentition 

 simulating that of the scarids under a new generic and specific desig- 

 nation, viz, Clioerojulis castaneus.X 



Thysanocheilus was sui)posed to be "most nearly allied to Lahrichthys 

 cyanotwnia Bleek (Atlas i. Tab. 22, Fig. 1), but " in this the lower lip only 

 is fringed, and there is only one canine in the upper jaw, at the angle 

 of the mouth," etc. 



Chcerojulis was supposed to agree with Thysanocheilus generally and 

 in lip structure, but to differ in dentition. 



The supposed differences between the several genera in question were 

 subsequently negatived, and Labrichthys, Thysanocheilus and Chcerojulis 

 were identified as generically identical and even based on the same 

 species. 



In 1867, Dr. Steindachner, having obtained a better jireserved speci- 

 men of Chcerojulis castaneus, recognized its identity with Labrichthys 

 cyanoUenia in the following terms: 



Chocrojulis castanea^ Kn. Steind. . . . ist, wie ich mich aus der Untersuchung eines 

 spiiter eingesendeteu grosseren und besser erbalteuen Exemplares iiberzeugte, ideu- 

 tiscb init Labrichthys ci/anotonia Blkr. Die Bezabnung der Kieferstiicke und die Lip- 

 peubildung ist bei dieser Art so wesentlich verscbieden voii der iibrigeu Lahrichthijs- 

 Arteu, welcbe Giintber im Cataloge der Fisebe des brit. Museums anfiibrt, dass icb 

 sie nach Bleeker's Vorgaugo in das Gescbleobt PseudoJahnts vereinige, fiir welcbe

 duug findet, Aviibrend das Gescblecbt Lahrichthys=^Churojidis Ku. Steiud. zuerst von 

 uns genau gescbildert wurde.|| 



* The only extralingual deviation between tbe Englisb (1880) and German (1886) 

 editions of tbe Introduction relates to Creniiahrus, viz : 1H80, p. ft27 : "Tbe range of 

 tbis genus is co-extensive witb Lahruxs. C. mclops, tbe ' Gold-sinny,' or ' Cork-wing' is 

 coninion on tbe British coasts." 1H86, p. 376: "Die Verbreitung dieser Gattung fiillt 

 mit der von Labrus zusamnien. Von den dreizehn bekannten Arten sind die meisten 

 besonders im Mittelmeere gemeiu."
