fin: second dorsal very small, inserted much nearer to the 
tip of the tail than to the origin of the first dorsal, the 
length of its base 3 in that of the first dorsal and nearly 
4 of the posterior border. Anal fin inserted much nearer 
to the caudal than to the ventral and wholly in front of the 
second dorsal, its posterior border much shorter than 
that of the second dorsal and a little less than the basal 
length, which is 23 in its distance from the precaudal pit- 
Caudal fin long, its upper border 17, time the length of the 
head and 44 in the total length ; terminal border convex, 
2} times the lower border behind the notch, its upper angle 
acute ; descending lobe of lower border well developed 
and subfalciform, originating slightly in advance of the upper 
precaudal pit ; its anterior border 2} in the space between 
its origin and the notch, which is 1% time its distance from 
the origin of the anal. Pectoral fin moderate, extending 
when appressed to below the origin of the first dorsal, its 
anterior border linear, except at the extreme tip where it is 
bent downwards, its upper angle pointed; outer border 
emarginate, the lower angle rounded ; posterior border 
sublinear ; width of fin from outer inferior angle to middle 
of anterior border + of its outer border. Ventral fin rather 
small, its origin $ nearer to the anal than to the pectoral 
all the edges linear, the angles obtusely pointed. Dark 
ashy blue above, gray beneath: pectoral and ventral fins 
outwardly edged with ash-gray: iris white. (Named for 
Professor David Starr Jordan, of the Leland Stanford Junior 
University, in remembrance of his flying visits to Brisbane 
in May and June, 1907).
