 SEAS EXPEDITION OF 1929, WITH DESCRIPTION OF 

 ONE NEW GENUS AND THREE NEW SPECIES 



By Henry W. Fowler

The fishes reported upon in this paper form the collection obtained 

 by Gov. Gifford Pinchot's expedition of 1929 to the South Seas. 

 Briefly, the course of this expedition was across the Caribbean Sea, 

 through the Canal Zone, thence to Cocos Island and the Galapagos 

 and Marquesas Groups, and finally to Tahiti, Society Islands. Most 

 of the fishes were obtained in the Galapagos and Marquesas Groups, 

 largely through Dr. A. K. Fisher, of the United States Biological 

 Survey. Dr. Henry A. Pilsbry, of the Academy of Natural Sciences 

 of Philadelphia, also accompanied the expedition and obtained a 

 number of fishes forwarded to Philadelphia. In the following pages 

 I have mentioned these materials as in the academy, as it may be 

 understood that otherwise the specimens are in the United States 

 National Museum. 



The collections include 69 determined species, many of which are 

 interesting or valuable records for distribution. The following are 

 described as new: Benthosema pinchoti^ new species; Ophiohlen- 

 nius pinchoti^ new species; Giffordella^ new genus (Blenniidae) ; 

 Giff ordella comeliae^ new species. 



Family EULAMHDAE 



EULAMIA GALAPAGENSIS (Snodgrass and Heller) 



One fine young example, 565 mm. long, an embryo from a female 

 2,592 mm. long, taken in Chatham Bay, Cocos Island, June, 1929.^ 

 Of the large female, portions of the left pectoral fin, upper teeth, and 

 piece of skin are preserved. The teeth are broadly triangular, their 

 outer edges slightly concave, and all edges finely serrate. 



'All dates herein are 1929.
