DEVELOPMENT AND LIFE HISTORY OF SOME TELEOSTS 
573 
Specimen 18 mm long. — Only one specimen of this size is at hand, which is the 
largest post larva in the collection. Development has progressed rather slowly and 
is about in the same stage as a boleosoma of a length of 10 to 12 mm. The body has 
become rather more robust, the depth being contained in the length to base of caudal 
about 8.0 times. The spinous dorsal is partly developed, five slender spines being 
present, whereas in the fully developed individuals the normal number is six. The 
ventral disk is quite well formed and reaches about half the distance from its base 
to the vent. This specimen, like the smaller ones, is void of color. The transparent 
air bladder with the dark membrane over it remains visible through the abdominal 
wall (fig. 73). 
DISTRIBUTION OF THE YOUNG 
The number of specimens taken is entirely too small to permit drawing a con- 
clusion in regard to the distribution of the young of this species. Eight of the 14 
specimens from Beaufort were collected off Beaufort Inlet, while the others were 
taken in the harbor and a neighboring estuary. The 23 specimens collected by the 
Grampus were all taken offshore. The young, therefore, may be expected along the 
outer shores, as well as in inside waters. 
Only two specimens were taken in surface towings at Beaufort, all the others 
appearing in bottom hauls. Of the 23 specimens collected by the Grampus 21 were 
taken on the bottom. This information is missing for the other specimens. It seems 
probable, therefore, that the young may occur at any depth in the water inhabited, 
but that they are most commonly on the bottom. Nothing can be reported at this 
time concerning the rate of growth. 
FAMILY BLENNIIDAE. THE BLENNIES 
Three species of blenny, namely Hypsoblennius hentz, Hypleurochilus geminatus, 
and Chasmodes bosquianus are common on the coast of North Carolina. The develop- 
ment of the eggs of all these species has been studied, and also the development of 
the young of the first two named. The young of C. bosquianus, a species less common
