404 LA.liRICHTHYS AND PSEUDOLABRUS GILL. 



AUSTROLABRUS. 



Auslrolahnis Steiudacbner, S. B. Akad. Wiss. [Wien], 1. Abth., v. 88, p. IIOJ (Ich. 

 Beit. XIII, 38), 188.3. 



Pseudolabri with dorsalis aud analis covered •with scales at bases 

 and angulated behind, and with veutrals angulated and the first ray 

 longest.* 



By Dr. Steindachuer this type was considered to be at least sub- 

 generically distinct from the Pseudolabri, on account of the scaly dorsalis, 

 analis and caudalis.f

EUPETRICHTHYS. 



Eupetriclithys Ramsay and Ogilby, Proc. Liun. Soc. N. S. Wales (2), ii, 631, 1887. 



Pseudolabri with dorsalis and analis naked and ventrales angulate 

 and with the first ray elougate. 



According to Messrs. Eamsay and Ogilby, " its close affinity to 

 Labrichthys [i. e., Pseudol abrus] is at once apparent, but in such a genus, 

 where the fin formula remains constant throughout the whole series 

 of about thirty§ species, any departure from the normal number must 

 necessarily carry with it a grea ter weight then among fishes which enjoy 

 greater latitude in this respect." This difference, therefore, coupled 

 with the elongate ventral s and ge neral form, || has induced the authors 

 to propose the genus. 



Only one species is known, viz : U. angiistii)es E. & O., 1887, 632.

It may be added that the Labrichthys bicolor of Day (Proc. Zool. Soc. 

 London, 1870, p. 095) is the Remigymnus melapterus of Bleeker as was 

 later recognized by Day himself (F. I., 1877, 396). 



*A. maculatm has D. ix+12, A. iii+lO. 



tDurchdie starke Beschnppuug der Dorsale, Anale und Caudale imterscbeidet sich 

 die bier boscbriebeiie Art so aufFalleud von der Mebrzabl der iibrigen Labricbtbys- 

 Arteu, dass eie miudestens als Repnisentaut einer besoudereu Unteigattunjj ( A usirola- 

 Irus VI.) betracbtet werden muss. — Steindachner. 



tl can only account for tbe use by Dr. Stcindacbner of tbe name Labriclithijs for 

 tbis type by tbe supposition tbat in tbe lonjj interval of time between bis repudiation 

 of tbe name and tbe description of tbe new species be bad forgotten bis former con- 

 clusions (see p. 398). Tbe facts certainly bad not changed meanwhile, and no 

 species intermediate between Labrichthys and I'seudolabrus had been discovered. 



^ Tbe examination of a more extended series of specimens will probably reduce 

 this number somewhat.— R. & O. 



\\E. angnstipca has D. ix+l^ and A iii-fll, while typical Pseudolabri have D. 

 ix+11 and A. iii-f-lO. " Tbe greatest height of tbe body, wliicb is behind the origin 

 of tbe anal tin," is contained in the total length 5^ times, while the head is 5 

 times.
