left side are placed closely together but the rest, including all of those on the 
right are evenly spaced. Schulte and Smith (1918, p. 11) state that, in the foetas 
examined by them, ‘‘ our hairs, arranged in an oblique line, were present in front 
of the eye,’’ and state further that the intervals suggest a fifth in the middle 
of the series. Allen (1941, p. 28) found im his foetus, ‘‘four short, tapering 
bristles placed in an oblique row in front of each eve.’’ The last-named author 
describes five well-marked grooves on the throat but in the specimen now recorded 
the skin in this area is perfectly smooth, possibly due to its earlier stage (text fig. 5, 
lower right).

Fig. 6-9. Male foetus from Port Victoria; 6-8, dorsal, pectoral and caudal tins (X 114) ; 
9, tracing of X-ray of head and thorax to show. position of skull, ete. (34 nat. size). 

The body of this small foetus is a little more than four times as long as deep. 
The dorsal fin is not faleate but is triangular and low, being considerably less than 
three times as long as high (text fig. 6); if is placed distinctly posterior to the 
middle of the length. The pectoral limb is not quite two and one-half times longer 
than deep; the digits are visible through the thin exterior tissues but an X-ray 
photograph discloses no ossification of phalanges, etc. (text fig. 7). 
The caudal fin (text fig. 6) has not yet developed backwardly flaring flukes, 
the posterior margin of the fin being convex; the lateral edges are almost straight 
and a small median posterior notch is present. 
A photograph of the foetus secured immediately after removal from the 
uterus accompanied the writer’s original brief record of the Port Victoria material 
(Hale, 1989, p. 7). 
The measurements given herein for it are taken from the formalized specimen ; 
its total length before preservation was slightly greater, viz. 203-2 mm. It should 
be added that the measurement from tip of snout to anus is 132 mm.
