606 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 113 
single shrimp obtained by the Hopkins Stanford Expedition in 1898 
and by the absence from the Scripps collections of two of the shrimps 
obtained during the Presidential Cruise. 
I am very grateful to Conrad Limbaugh and other members of 
the Scripps Expeditions for placing this interesting material at my 
disposal. Most of it has been deposited in the national collections; 
a duplicate set, where available, has been sent to the Museum Na- 
tional d’Histoire Naturelle in Paris. The brachyuran decapods 
collected by the Scripps Expeditions are being reported upon sepa- 
rately by John S. Garth of the Allan Hancock Foundation, University 
of Southern California. 
In addition to the species listed below, the Scripps collections 
contained two unidentifiable alpheid shrimps. One is a species of 
Automate, represented by two female or immature specimens lacking 
most of the pereiopods. The other is a species of the Paulsoni Group 
of Synalpheus, represented by a similarly incomplete specimen. 
Family Penaeidae: Subfamily Penaeinae 
Metapenaeopsis kishinouyei (Rathbun) 
Parapenaeus kishinouyer Rathbun, 1902, p. 288, pl. 12, figs. 13-15. 
Penaeopsis kishinouyet Schmitt, 1924, p. 161. 
Penaeopsis (Metapenaeopsis) kishinouyet Burkenroad, 1938, p. 72, figs. 16, 17.— 
Anderson and Lindner, 1945, p. 310. 
MateriAu: East end, coral reef; August 15, 1958; Sta. W58-289; 
Reese, Baldwin, and Wintersteen; 1 female. 
MEASUREMENTS: Carapace length, 7.5 mm. 
ReMARKS: This specimen agrees very well with female syntypes of 
similar size with which it has been compared. In males and immature 
females, the tips of the rostral teeth form a convex line, as noted by 
Rathbun, but they form a nearly straight line in mature females. 
Kubo (1949) and Dall (1957) have been followed in considering 
Metapenaeopsis of generic rather than subgeneric rank. 
DistRiBuTION: Previously recorded from the Galapagos and 
Revilla Gigedo Islands. 
Family Palaemonidae: Subfamily Palaemoninae 
Brachycarpus biunguiculatus (Lucas) 
Palaemon biunguiculatus Lucas, 1849, p. 45, pl. 4, fig. 4. 
Brachycarpus biunguiculatus Schmitt, 1939, p. 13, fig. 1—Holthuis, 1952, p. 3, 
pl. 1. 
Materia: Northwest shore, rocks south of landing place; July 
21, 1938; Sta. 9; W. L. Schmitt; 1 female.—Poison; October 20, 1956;
