56 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 92 
On the abdominal somites intermediate, lateral, and marginal 
carinae are discernible; on the fifth and sixth the intermediates are 
more plainly marked than on the preceding somites; the sixth somite 
is the only one with submedian carinae; the carinae of this somite are 
all spined. : 
The telson is wider than long; the median carina has two spines, 
the proximal one the smaller, the distal one much larger, the carina 
ending at the median V; the submedian carinae extend from near 
the base of the telson onto the dorsal surface of the submedian teeth. 
These with the exception of the marginal are the only carinae on the 
telson, the surface of which is otherwise slightly punctate and shin- 
ing. The denticles number 7, 8-9, 1. The bifurcate process of the 
uropods bears 10-12 spines on its inner margin; the inner of the 
two projections is about twice the length of the outer; it carries a 
large rounded-tipped tooth on its outer margin. The submedian 
spines of the telson have movable tips. 
Color in alcohol.—Cream, with brown chromatophores more closely 
grouped on distal median margins of all thoracic and abdominal 
somites. 
Measurements.—Body length overall, exclusive of rostrum, 35.6; 
carapace length 8.1, anterior width 4.5; rostral length 1, width 1.5; 
lengh of telson 4, width 5.5. All measurements in millimeters, 
Material ewamined—Known only from the type specimen. 
Remarks.—This small stomatopod shows some divergences from 
the norm as exhibited in part by Hansen’s S. ambiqua and S. incerta.? 
These consist in the main of the shape of the cornea, the spined 
antennules, and the enlarged antennular acicle, characters that in 
S. oculinova are somewhat unique for the genus. In Schmitt’s key 
in the Hancock report (op. cit., p. 140) it would fall near his S. 
swetti, the major differences being as above stated.
