INTRODUCTION 
At various times the authors (Hildebrand, 1919-20, and Ginsburg, 1922-24) 
were stationed at the United States Bureau of Fisheries Biological Station at Key 
West, Fla., where they gave attention to the collection and study of fishes. The 
present short paper sets forth the data obtained from some of the collections. 
Myrophis punctatus Liitken 
Liitken, Vidensk. Meddel., Nat. Foren. Kj0benliavn, 1851, 1. 
One specimen, 150 millimeters long, was taken in a muddy pond. This appears 
to be the first record of this species for Key West. 
Fundulus ocellaris Jordan and Gilbert 
Jordan and Gilbert, Proc., U. S. Nat. Mus. 1882, 255. 
This fish was quite abundant on April 11, 1919, in a brackish swamp, nearly dry 
in which many fish were dying. The ocellus is lacking on the dorsal fin of one female 
Three specimens were measured with the following results: D. 11 to 12; A. 9 to 10; 
scales 34 to 35; depth 4.35 to 4.5; head 3.1 to 3.35; eye 3.3 to 3.4; snout 3 3 to 3,5, 
maxillary 3.4 to 4.4; pectorals 1.80 to 1.97. This species apparently has n^t pre- 
viously been recorded from Key West. 
Menidia conchorum n. sp. 
Diagnosis . — Anal soft rays 11 to 14, the modal frequency being 12; 33 to 35 
vertical rows of scales ; origin of spinous dorsal nearer to base of caudal than tip of 
snout; eye larger than length of snout; base of anal distinctly shorter than head; 
size small, the smallest known Menidia.
