of caudal fin; posteriorly the spots have a tinge of blue; spots on head very small, those posteriorly 
larger, but none nearly so large as pupil; dorsal, ventral and pectoral fins transparent. 
Color in alcohol dark brownish black; back and sides profusely covered with small, round, or 
stellate bluish white spots, uniformly disposed; ventral surface paler, the lighter spots and markings dis¬ 
posed to run together, forming reticulations; cheek with few or no spots; caudal peduncle brown, with 
somewhat larger, round, or oblong bluish white spots; base of dorsal black, the fin dusky; base of 
anal pale brownish, with a few small white spots, the base of the rays with a brown line, the fin 
dusky; caudal dark at base with a few white .spots, the distal portion paler; ventrals dusky. 
This is a species of wide distribution, having been recorded from the Indian Ocean tod Archipelago 
and from various places in the tropical Pacific. Steindachner had 1 example from Honolulu, Jenkins 
has 2, and we have 5, all from the same place. Others were obtained by the Albatross. Jenkins also 
had 1 from Ililo and there is 1 from Hilo in the California Academy.

Genus 201. LACTORIA Jordan & Fowler. 
This genus agrees with Ostracion in having the carapace 4-angled, but differs in having strong 
spines in front of the eyes and a pair terminating the ventral keels; a median dorsal spine is some¬ 
times present.

Head measured to gill-opening, 3.7 in length to base <»f caudal; depth 2.3; eye 2.7 in head; snout 
4.6; I). 9; A. 9. 
Anterior profile of head very steep, interrupted by a constriction one-third of distance between 
tip of snout and middle of interorbital space; interorbital space V-shaped, when viewed from before, 
the depression extending almost to a level with upper edge of pupil; carapace with 5 ridges, the dorsal 
ridge scarcely evident, with a large spine located midway between tip of snout and base of caudal fin; 
dorso-lateral crest with 3 spines, the anterior projecting upward and forward from the orbit; the 
posterior located slightly behind middle of dorsal spine, midway between anterior edge of orbit and 
posterior end of carapace; the median, which is small and weak, located somewhat nearer to the 
orbital than the posterior spine; ventro-lateral ridge with 4 spines, the first very small, the second 
larger, located below dorsal spine, the posterior one projecting backward, the distance between it and 
the one of the opposite side equal to distance between center of pupil and dorsal spine; ventral 
surface of carapace convex, a slight median depression extending from breast to anal tin; plates 
granular, except 10 or 12 in the region posterior to pectoral fin, each with a central granule usually 
larger than the others. 
Dorsal fin located midway between dorsal spine and end of carapace; base of anal fin occupying 
most of the space between vent and end of carapace; pectoral just behind vertical through posterior 
edge of orbit. 
Dorsal portion of body dusky with small dark spots scattered over snout and back; ventral half 
of carapace translucent with zigzag dusky bars along the region of crest, the color following the 
vertical sutures between the plates; throat and breast with scattered dusky spots somewhat smaller 
than pupil.
