﻿MARINE ASELLOTE ISOPODS — MENZIES 141 



pods not exceeding half the pleotelson length. Male first pleopods as 

 in /. k. Mncaidi. First and second antennal articles considerably short- 

 ened compared with those of /. h. Mncaidi (compare figures 57, e, 

 and 57, /). 



Types. — In the collections of the Zoological Museum of the Academy 

 of Sciences, U. S. S. R., from Komandorskie Islands, Bering Sea. 

 Male, length 2.5 mm., width 1.0 mm. 



Geographical distribution. — Komandorskie Islands, Bering Sea, to 

 Monterey County, Calif. 



Material examined. — I have examined 47 male and 46 female speci- 

 mens, from various localities in northern California. 



Ecology. — See remarks for /. k. Mncaidi. Ovigerous specimens 

 were collected during February, May, and June. 



Remarks. — Gurjanova makes no mention of the two coupling hooks 

 present on each maxilliped. Her figures of the abdomen of the species 

 do not compare favorably, the uropods shown in figure 5, a, being con- 

 siderably longer than those shown in figure 5, e. Presumably both 

 figures are of the same species. In most respects her description and 

 figures indicate that the specimens I have seen are identical with 

 her species. I consider this form a subspecies of /. k. Mncaidi (see 

 remarks concerning that subspecies). 



lANIROPSIS ANALOGA, new species 

 FlGTTEES 60-62 



Janira maculosa Leach, Hatch, 1947, p. 171, not figs. 37-38, 



Holotype. — Male, length 3.7 mm., width 1.0 mm. 



Allotype. — Length 2.5 mm., width 0.8 mm. 



Diagnosis. — Cephalon with frontal margin slightly trilobed. 

 Pleotelson with 4 (juvenile specimens) to 7 (adult specimens) spine- 

 like serrations on either side above uropods. Uropods somewhat flat- 

 tened, exceeding three-quarters the pleotelson length. Flagellum of 

 first antenna composed of about 10 (average) subequal articles. Each 

 male pleopod with expanded lateral apex pointed, posterior margin 

 gently curving posteriorly. 



Character of hody. — Body speckled with numerous black chromato- 

 phores. Epimeral and pleotelsonal setae give borders of body a hirsute 

 appearance. Eyes black in life. 



Pleon. — Posterior margin lacking acute posterolateral angles. 



First antenna. — Flagellum with 5 to 15 subequal articles. 



Second antenna. — About as long as body. Flagellum with about 63 

 subequal segments. 



Maxilliped. — Palp of male and female similar. 



First maodlla. — Outer lobe with 12 setae, inner lobe with 4 apical 

 setae.
