II. Group with gastric region depressed below the general level of the carapace. 

 Antennal scale with the blade exceeding the spine, except in C. variabilis, 

 in which the spine equals or exceeds the blade, and in C. lomae, in which 

 the spine exceeds the blade. {The second lateral carina of the carapace 

 counting from the middle, is unarmed in all the species in this group except 

 C. munitella, in which it is armed with a spine situated a little behind the 

 superior lateral spine.)

Fig. 66. Crago munita, <$, X 2; a, lateral view of carapace; b, dorsal view 

 of carapace and abdomen (from Bathbun, U. S. N. M.). 



Characters. — First to fourth abdominal segments inclusive, smooth. Carapace 

 less than two-fifths the length of the abdomen; anterior median spine of the 

 carapace not advanced as far as the line of the orbits. Bostrum short, reaching 

 to a line between the tips of the orbital and the anterolateral spines, nearly 

 horizontal, medially sulcate, tip rounded. Hands oblong, narrowing a little 

 distally or presenting a slight constriction at the base of the spine, three times 

 as long as wide. 



Dimensions. — Type: length of body 46.6 mm., of carapace 12.7 mm. 



Type Locality. — Puget Sound. 



Distribution. — Port Etches, Alaska, to San Miguel Island, California, 12 to 

 114 fathoms. 



Bemarks. — Dana described the abdomen as smooth. The carina of the fifth 

 segment is very indistinct in the female, while Dana in his figure indicates two 

 carinae on the sixth segment (Bathbun).
