(c) A specimen (lill'evontly crushed 3), the trunk l)eing prohal)ly 
about normal, the form and proportions of the liead altered by the 
expansion of the mouth. 
(d) The type specimen (Fig. 4), a Ayell-preserved fisli exhibiting all the 
bus. The trunk is a little distorted, as sho\yn by the displacement 
of the neural arches and yertebral rings in the abdominal region. 
(e) A large fish (Fig. 5) with the trunk much deepened by distortion, 
the ribs being torn away from the yertehrm and the yentral border 
especially displaced. 
(/) The head and abdominal region in counterpart, one side drawn of 
the natural size (Fig. 0) to exhibit the axial skeleton of the trunk. 
(r/) llemains of the hinder half of a rclatiycly large fish (Fig. 7), probably 
of this species. 
(//) Fragment of fish displaying the pclyic ilns with tlieir supports, as 
shown of the natural size in FTg. 8. 
'riie principal features in tlic drawings arc well emphasised, and the 
detailed description of the osteology of the genus giyen aboye renders any 
further account su])eriluous. 
fS'p. Char . — A robust species, ordinarily attainiiig a length not 
exceeding 0T5. Length of head witli o})('rcnlar apparatus less than the 
maximum depth of the trunk, and somewhat less than one-tifth of the total 
length of the bsh ; caudal pedicle robust, nearly lialf as deep as the abdominal 
region. Vertebra' about forty-fiye in number, the centra scarcely longer than 
deep in the anterior part of the caudal region, and forming thin, smooth, 
constricted cylinders ; the neural and hmmal arches in the anterior part of 
the caudal region gently arcuated, not depressed. Felyic tins arising slightly 
nearer to the anal than to the pectorals ; dorsal with about twelve rays, 
arising in advance of the middle point of the back and immediately behind 
the origin of the pelvic tins ; anal fm, with about nine rays, arising half-way 
between tlie pelvic and caudal tins. 
Leptolepis Lowei, sp. nor. 
Plato A"I, Pigs. 9, 10. 
OJjs . — A rare new species of Leptolepis is indicated by a few specimens, 
of which two are enumerated below ; and it may appropriately receive the 
name of L. Loicci, in honour of the original discoverer of the Talhragar 
tislies : — 
(a) The ty 2 )e specimen, slunvn of the natural size in PI. VI, FTg. 9. The 
u])ward displacement of tlic neural arches in the al)dominal region 
suggests that the trunk had been somewhat dec'pened by crushing.
