Metapenaeus mogiensis (Rathbun). 
(PL xx, fig. 3.) 
Parapenseus mogiensis Rathbun, Proc. U. S. Nat. Mus., NXVI, 1902, 39, text figs. 6-8. 
South coast of Molokai Island fathoms, station 3851, 1 male and I female of medium size. 
Superficially has great resemblance to M. velutinus, but the carapace is relatively shorter; sixth 
jdominal segment shorter, eyes smaller, less than half as long as acicle. 
Metapenaeus richtersii (Miers). 
(PL xx, fig. 2.) 
Penxus richtersii Miers, Zool. Alert, 564, pi. i.ii, fig. A, 1884. 
South coast of Oahu Island, surface, electric light, station 
3812, 1 male and 1 female; Pailolo- Channel, surface, electric light, 
station 3860, 1 female. 
The rostral teeth may be five or six, and in our specimens 
only one of them lies behind the orbit. The gastric tooth is about 
at anterior fourth of carapace. Rostrum higher, less acuminate 
than shown in Miers’ s figure. The posterior half of the fourth 
abdominal segment, as well as the fifth and sixth segments, is 
carinate; sixth segment terminating in a small spine. 
Antennal flagellum as long as body exclusive of telson. Outer maxillipeds very much flattened 
and reaching only to end of antennal peduncle. 
A spine on basis of first pair of legs but none on ischium; no spines on second or .third pairs. 
Fifth pair of legs exceeding the fourth by the length of the dactylus. 
The petasma is symmetrical, similar to that of M. affinis (Milne Edwards)." 
In a ventral view the terminal lobe on each side is followed on the outer margin 
by two lobes instead of one. 
Our largest specimen, female, measured 42.8 mm. long, carapace 12.4.

Metapenaeus evermanni, sp. nov. 
~ (PL xx, fig. 1.) 
A stout, pubescent species, with general appearance of M. lamellatus (de 
Haan), from which it differs in a less arched and lower rostrum, only one of 
whose eight teeth is situate behind the orbit; the gastric spine farther forward 
at the anterior two-fifths (rostrum exclusive) instead of at the middle of the 
carapace; a longer outer maxilliped, which exceeds the acicle by length of 
dactylus; the sternum of the female, while possessing a pair of spines between 
the bases of the feet of the second pair, and a single spine between those of the 
fourth pair, has also a spine between the feet of the fifth pair. 
All the legs are provided with exopods, only the first to third pairs with epipods. 
Dimensions of female type. — Length of carapace and rostrum 18.5, of abdomen 40 mm. 
Type-docality. — One specimen only was obtained on the south coast of Molokai Island, 73 to 43 
fathoms, station 3849 (Cat. No. 30539).
