THE PYROSOMIDS 



Dr. Hoyt S. Hopkins, of New York University, kind- 

 ly determined the Pyrosomids collected. 



January 3, 1929, latitude 31° 54' south, longitude 

 88° 17' west, station 64, sample 397. Pyrosoma spin- 

 osum Herdman. Two, or more (?) incomplete colonies. 

 Represented by one tubular part of a colony, broken at 

 each end; length 50 cm; diameter of tube (flattened), 6 

 cm at wider end, 5 cm at narrower end, tapering uni- 

 formly. Also, another fragment, not tubular but torn 

 open, of about 60 cm length; and two short tubular parts, 

 apparently belonging to this same colony, having a di- 

 ameter of about 11 cm. The largest ascidiozooids are 

 7 mm long, and have 20 to 25 branchial crossbars; tes- 

 tes immature; ovaries not seen, probably not developed. 



June 29, 1929, latitude 37° 40' north, longitude 145° 

 26' east, station 115, sample 694. Pyrosoma sp. An im- 

 mature colony, of 12 ascidiozooids; belonging to the sub- 

 genus Pyrosomata ambulata, but too young to be identi- 

 fied as to species. Length of colony 3 to 4 mm, diame- 

 ter 2 to 3 mm. 



April 24, 1929, latitude 08° 43' south, longitude 170° 



56' west, station 95, sample 564. Pyrosoma sp. A pri- 

 mary zooid colony of two primary ascidiozooids, the 

 two other primary zooids (of the "tetrazooid colony") 

 having degenerated, as shown by the persistence of two 

 extra pairs of test vessels near the colony opening. 

 Colony nearly spherical, about 2 mm in diameter. Be- 

 longs to the subgenus Pyrosomata ambulata, but is not 

 identifiable as to species. 



October 3, 1929, latitude 23° 27' north, longitude 

 159° 27' west, station 140, sample 858. Pyrosoma sp. 

 An immature colony, of 12 ascidiozooids, and four buds 

 forming on primary ascidiozooids. Colony nearly spher- 

 ical, 3 to 4 mm in diameter. Belongs to the subgenus 

 Pyrosomata ambulata, but is too young to be identified 

 as to species. 



September 15, 1928, latitude 12° 54' north, longitude 

 56° 15' west, station 30, sample 190. Pyrosoma sp. A 

 primary zooid colony of three primary ascidiozooids. 

 Colony nearly spherical, about 2 mm in diameter. Be- 

 longs to subgenus Pyrosomata ambulata, but is not iden- 

 tifiable as to species. 



THE LIZARD 



A specimen of lizard which was included in the ma- 

 terial has been identified by the Assistant Curator of 

 Reptiles and Batrachians of the Smithsonian Institution 

 (Miss Doris M. Cochran) as Cryptoblepharus poecilo- 



pleurus, which belongs to a group which is distributed 

 widely over the tropical regions of both hemispheres. 

 It was taken under a stone on land at Easter Island De- 

 cember 9, 1928, between stations 53 and 54.
