The whole of the upper surface of this rare and beautiful crustacean is 
marbled, in its dry state, with yellowish brown spots on a dark brown ground, 
while the tips of the caudal appendages are a vivid red. 
Length, from tip of rostrum to tip of movable spines, 3.80 inches; of 
carapace only, 0.82 inch; width of abdomen, 0.63 inch. 
This single specimen in this collection was found at low tide, on sandy mud 
flats at San Diego. 
This and Squilla De-saussurei, Stimpson, are, so far as I am aware, the only 
Stomapoda yet discovered on the shores of California. 
Crangon nigromaculata. 
Carapace with a single spine on the gastric region near the rostrum, and 
a larger spine on each hepatic region. Suborbital and antennal spines pres- 
ent. Inner antenne about equal in length to movable scale of outer anten- 
ne, and the base of outer antenne about half as long as its movable scale; 
Dactylos of first pair of feet transverse, short; an oval black spot on each 
side of the abdomen just anterior to the caudal processes. 
Three specimens from San Diego, dredged in six fathoms of water. 
Total length of largest specimen from tip of antennal scale to tip of tail, 
27% inches; of body from tip of rostrum, 2.06 inches. 
This species can readily be distinguished from all others by the black spot 
upon each side of the tail; it appears to be nearly allied to C. nigricauda.— 
Stimpson. 
Crangon Alaskensis. 
Rostrum very short and pointed; spines of carapace, as in nigromaculata: 
inner antennz scarcely as long as movable scale of outer antennze; movable 
finger of first pair of legs rather long, oblique; hands, carapace, and abdo- 
men in preserved specimens (alcoholic), clothed with minute black spots. 
This species may be distinguished from C. nigricauda, which it much resem- 
bles, by the greater obliquity of the palm of the hand, the different coloration, 
and the smaller size. 
Length of body, 1.45 inches. 
Several specimens from Mutiny Bay, Alaska, presented by the U.S. Coast 
Survey. 
Alpheus bellimanus. 
At the time of the publication of Stimpson’s Crustacea and Echinodermata 
of the Pacific Shores, no species of Alpheus had been detected in California, 
but recently two species have been collected by Mr. Henry Hemphill, of 
San Diego. The present species may be easily recognized by the beautiful 
coloring of its hands, which, in a dried specimen, are orange, with various 
spots and Briings of black and white. 
Movable finger of larger hand small, depressed, and closing in a plane 
oblique to that of the manus, which is furnished with a spine on its outer
