MM. 
Fig. 8. Diplospinus multistriatus 10.0 mm in standard length. 
Pigment consists of the distal brown spot in 
the spinous dorsal, large melanophores on top 
of the head and occiput, and diffuse brown color 
anterior to the eye, posteriorly on the maxillary, 
in front of the pelvic bases, and on the branchio- 
stegal membranes. 
Definite indications of the forthcoming rib- 
bon shape are seen in the 17.4-mm postlarva 
(Fig. 10). There is little trace of the earlier 
abdominal distension and the head is relatively 
short. The adult fin ray complement has been 
attained, although the fins are immature in that 
their spines still bear spinules. The pelvics are 
still excessively large and the caudal is well 
forked. 
On the head, the preopercular spines are as 
before except that those on the lower limb are 
shorter and stouter. The opercular ribs and
