NO. 12 THREE NEW AM PHIPODS— SHOEMAKER 3 



The female closely resembles the male except in the following- 

 characters. First thoracic segment not produced beyond the head. 

 Peraeopod 3 with second joint somewhat shorter, and the serrations 

 of upper margin extending only about half its length; third to 

 seventh joints combined a little over half the length of the second 

 joint. 



WESTWOODILLA LONGIMANA, n. sp. 



This specimen is not perfect, but I believe there is quite enough 

 to establish the species. Only parts of the antennae are present. The 

 last three pairs of peraeopods and the last two pairs of uropods are 

 missing. This species appears to be nearest to WestwoodiUa rcct'i- 

 rostris as figured by Chevreux.^ 



Head with frontal process rather short, strongly arched, and ending 

 in a short, outward-curved rostrum. Eyes apparently large but very 

 poorly defined. Side-plate i not projecting so far forward as shown 

 by Chevreux for W. rectirostris. Gnathopod i about as shown by 

 Chevreux for W. rectirostris. Gnathopod 2 with fifth and sixth 

 joints subequal in length and very elongate. Palms of gnathopods 

 defined by a shallow notch and a long slender spine. Peraeopods i 

 and 2 alike, sixth joint obliquely truncate and bearing many long, 

 curved, terminal spines. Telson oval, apex slightly flattened and 

 bearing several minute spinules. 



Length. — About 5 mm. 



Holotype. — U.S.N.M. no. 68326, taken at station 84, latitude 

 i8°32'3o" N. to i8°39'oo" N., longitude 65°i8'3o" W. to 65°i7'oo" 

 W., February 26, 1933, probably 300 to 350 fathoms. The type 

 female was the only specimen taken. 



Remarks. — The frontal process is much more strongly deflected 

 than in Wcstzvoodilla rectirostris; the fifth and sixth joints of 

 gnathopod 2 are much more elongate than in W. rectirostris. As 

 figured by Delia Valle," the sixth joint of peraeopods i and 2 of 

 W. rectirostris is distally rounding and not obliquely truncate as in 

 W. longimana. Delia Valle figures the telson of W . rectirostris with 

 the lateral margins slightly concave, whereas in W. longimana the 

 telson is oval in outline. 



RHACHOTROPIS LOBATA, n. sp. 



Female. — Head, rostrum prominent, curving slightly downward, 

 apex rounding ; lower lateral corner nearly quadrate. Eyes rather 

 large and bulging laterally from the head. Antennae about normal.
