Dimensions.—Type, ovigerous female: length 25 mm. 
Color.—Abdomen with sixth segment darker colored than the others; a dark 
transverse band on the caudal appendages (Walker). One specimen was mottled 
brown with bright red markings along the back; the whole body of another was 
a dark slate color; another was banded with slate color, with center of body red; 
and still another had bands of slate and red alternating (Hilton). 
Type Locality—Puget Sound. 
Distribution—Puget Sound to Laguna Beach and Santa Catalina Island, 
California, 3144 to 40 fathoms. 
Biological Survey of San Francisco Bay—Crago munitella was 
dredged in 314 to’'7 fathoms, from a bottom consisting of angular rock 
fragments of various sizes, at two adjacent stations, D 57738 and. 5775, 
on each side of Yellow Bluff, south of Sausalito. At the latter station, 
C. munitella was in company with Scleroplax granulata, while at the 
former it was associated with Spirontocaris cristata, Crago nigricauda, 
C. franciscorum, and Cancer productus. The range of temperature 
and the salinity of the hydrographic stations which may be correlated . 
with the above dredge stations (as given in appendix III, p. 354) are 
respectively 11.0° to 13.5° C and 26.6 to 31.6. 
Genus Nectocrangon Brandt 
Rostrum wanting. Eyes nearly concealed or hidden by the carapace. Dactyls 
of fourth and fifth pairs of legs dilated and more or less adapted for swimming.

(from Rathbun, U.S. N.M.). 
Characters.—First and second abdominal segments not carinated; third and 
fourth segments only feebly carinated; each carina of the sixth segment term- 
inating in a small, sharp tooth or spine. Carapace with only two median spines 
behind spine on anterior margin which, outside of orbital fissure, is furnished 
with two spines close together instead of one as in the allied species. Antennal 
scale with spine extending only slightly beyond the blade. Hands from three 
and a half to four times as long as wide.
