three-lobed. Dorsal surface of telson with a broad unarmed median ridge, and on each 
side of this a more protuberant longitudinal and somewhat uniform prominence, which is 
convex on its lateral or external side, and concave towards the middle line. The telson 
has a median notch on its posterior edge, and on each side of this there are three obtuse 
rounded marginal spines, of which the submedian is farthest back, and the lateral most 
anterior. 
Length. — About three-fourths of an inch. 
Habitat. — A. Milne-Edwards records a single specimen of this species from St. 
Vincent, and Miers a single male from Mauritius, and two small specimens, without 
record of locality, from the “ Herald ” collection. 
Remarks. — In Milne-Edwards’ figures the carapace is represented rounded at its 
anterior as well as at its posterior angles, and nearly rectangular, and the fifth thoracic 
somite is represented with rounded lateral edges, as are all the other thoracic and 
abdominal somites. 
In my remarks on Protosquilla elongata I have given my reasons for regarding that 
species as distinct from this one.

Diagnosis. — Protosquilla with the two antero-lateral spines of the rostrum nearly as 
long as the median spine. The carapace is long, and nearly rectangular, with nearly 
rectangular antero- and postero-lateral angles. The fifth abdominal somite is longi- 
tudinally corrugated. The sixth is immovably united to the telson, although the suture 
is clearly indicated ; its dorsal surface is marked by six smooth rounded tubercles. On 
the dorsal surface of the telson there are three smooth rounded tubercles disposed in a 
triangle, with the median one anterior to the two laterals. The posterior margin is 
slightly notched in the middle, and is armed with very minute spines. 
Size. — About one and one half inches long.
