Rhinogobio Sleeker. Biol., Bulletin, xx, p. 371, pi. u, fig. 9. Scale elongate, with broad truncate base. 
Rohita Valenciennes. R. lineata from the Sittang River (E. W. Oates; B. M.), has elongated scales, 
about 10 mm. long and broad, the truncate base with a broad median lobe, bounded by the 
basal radii, which are two or three in number. Nucleus a short distance basad of center; gently 
curved delicate lateral radii; apical radii evanescent or extremely feeble; skin-covered area strongly 
tuberculate. The shape of the scale is very like that of Labeo fimbriatus. (PI. xxxin, fig. 9.) 
Saurogobio Sleeker. Zool. Anzeiger, xxxvi, p. 478. Scales elongated; those of 5 . dumerilii much 
like those of Rhinogobio typus; both species collected by Styan at Kiu-Kiang. 
Scaphiodon Heckel. Scales broader than long, with small subbasal nucleus; apical radii numerous, 
but no basal ones; interradial area tuberculate. I have two species from the British Museum, 
very much alike, but separable as follows; 
Base with a very prominent rounded lobe; laterobasal comers very distinct; skin pallid, speckled 
with light brown (Sind; F. Day) S. watsoni Day 
Basal margin convex, but not lobed; laterobasal comers indistinct; skin brown, speckled with 
darker (Muscat, Arabia; A. S. G. Jayakar) S. muscatensis 
Except for the broader scales and denser sculpture there is an evident resemblance to Capoeta. 
This resemblance doubtless extends to other than scale characters, for Cuvier and Valenciennes 
included species of Scaphiodon in Capoeta. S. muscatensis is figured on plate xxxin, figure 10. 
ScaphiodontichthysVinci^eirsL. My two scales of S. burmanicus, from Mount Mooleyit (Fea; B. M.), 
are both latinucleate; the scale is broader than long (about 7 by 8 mm.), considerably larger than 
that of Scaphiodon, with numerous apical radii but no basal; the basal margin is convex, without 
any lobe, and without laterobasal comers. The scale is stmcturally close to that of Scaphiodon. 
Schizo pygopsis Steindachner. I microscopically examined the skin of 5 . stoliczkae (Seistan, Helmiuid 
River, Col. McMahon; B. M.) and S. younghusbandi (Lhasa, Tibet, H. J. Walton; B. M.), but 
found no scales. The skin in 5 . younghusbandi is clear, profusely dotted with lichenoid spots of 
dark brown pigment. 
Schizothorax Heckel. Biol. Bulletin, xx, pi. iv, fig. 22 (S. biddulphii); Tiool. Anzeiger, xxxvi, p. 476. 
In 5 . intermedins (Kashgar; B. M.) the scales are elongate as in 5 . biddulphii, and the sculpture is 
in all respects the same, except that it is less dense. (PI. xxxin, fig. ii.) 
Semiplotus Bleeker. In Seniiplotus semiplotus (Cyprinus semiplotus McClelland, Semiplotus mac- 
clellandi Bleeker) from Assam (F. Day; B. M.) the scales are quite large, reddish, broader than long 
(length 13, breadth 15 mm.); nucleus a short distance below the middle; basal radii 3 or 4, feeble; 
slender curved lateral radii; apical radii very numerous, wavy; apical field coarsely tuberculate. 
The scale is of entirely the same general type as that of Barynotus luteus, but shorter, with much 
less prominent laterobasal comers, and fewer and feebler basal radii. The color is the same in 
both, and the differential characters cited are doubtless more or less variable. (PI. xxxin, fig. 12.)

Tinea Cuvier. Zool. Anzeiger, xxxvi, p. 476; Biol. Bulletin, xx, p. 373, pi. iv, fig. 21. 
Tylognathus Heckel. Day treats this as a synonom of Labeo. I have five species from the British 
Museum. They agree in having numerous apical radii and the apical field tuberculate. So far 
as the material goes, they appear to be separable as follows: 
The subquadrate scale broader than long (about 7 mm. long and 8 broad); laterobasal corners very 
prominent; basal radii very numerous, but fine and irregular; apical radii strong, more or less 
wavy, the interradial tubercles very strong T. {“ Lobocheilus”) lehat 
The subquadrate scale a little longer than broad (about 8 ram. long and broad); general charac- 
terslike the last, but apical radii scarcely wavy, and interradial tubercles weaker (Pata R. ; 
C. Hose) T. hispidus 
Scale conspicuously longer than broad, parallel-sided, shape like that of Labeo fimbriatus i 
I. Scale about 12 mm. long and 8 broad (Bowany R.; F. Day) T. ariza (Buchanan) 
Scale about 7 mm. long and 4 broad, but fish not adult (Madras; F. Day). . T. boga (Buchanan) 
Scale about 5L3 mm. long and 3X broad (Poona; Ifieut. Col. Playfair) T. striolatus 
The following Asiatic Labeo have scales of the Tylognathus type, or approximating it; L. sindensis, 
L.falcatus, L. bicolor, L. sladoni, L. ricnorhynchus , L. kontius (nearly shape and size of T. ariza, but less
