NO. 2133. FISHES TAKEN BY "ALBATROSS," 1RS8— THOMPSON. 469 



The genera of the group to which this belongs are in need of revi- 

 sion, it being evident that this species differs considerably from the 

 typical species of Clinus, and the forms at present Usted under this 

 genus in Australia and South Africa are very divergent also among 

 themselves, but no specimens are at hand for comparison. 



18. GENYPTERUS BLACODES (Bloch and Schneider). 



A specimen from Tome, Chile, 47 cm. long. This is assuredly the 

 ^'Opliidium hlancodes (Forst.)" of Tschudi,* which was figured by the 

 same author as "0. maculatum."^ The evidence for its identity with 

 Genypterus hlacocles Bloch and Schneider, from New Zealand, is 

 questionable. Hutton's description of the latter species ^ is possibly 

 not that of the present form, although it was of a much larger speci- 

 men (3^2 feet), because of these measurements: Head 7 in length, and 

 depth 10 in same. However, Hector, in the same paper * gives a 

 figure which is like our own specimens in measurements and other 

 characters. The Genypterus cMlensis recorded by Abbott from Chile ^ 

 is in the Stanford University collections and is plaiidy the same as 

 G. hlacoeles, although darker in color. There is no reason for regard- 

 ing Genypterus chilensis (Guichenot) as distinct from G. Placodes 

 (Bloch and Schneider), as far as can be seen. 



Our specimen shows the following characters: Head 4^ in total 

 length; depth 7; maxillary 2^ in head; eye 7; snout 5^; interorbital 

 breadth 5^; ventrals 2f ; pectorals 2po; D. about 120; A, about 127; 

 caudal rays 7; pectoral rays 25. Vertical fins dark; pectorals dark, 

 narrowly edged with white. 



19. LAEMONEMA MULTIRADIATUM, new species. 



Plate 4, fig. 3. 



A single specimen from Albatross station 2791, 38° 08' S. and 75° 

 53' W. off Lota, Chile, in 677 fathoms; total length 147 mm. It is 

 Cat. No. 76858, U. S. N. M. 



Head 4^ in length; depth at pectorals 6| (2f in head); width of 

 head If in its length; maxillary 2 in head; eye 4J; interorbital space 

 2J; snout 3; mandible If; distance tip of snout to ventral bases 1|; 

 ventral bases to anus 2-^-; anus to anal insertion 5|; snout to dorsal 

 insertion one and one-tenth times head length; length second ray of 

 first dorsal one and one-tenth times head length; of ventral filament 

 nine-tenths head length; D. 5-74; A. 71; pectoral 21; ventrals 

 with 2 long and 3 (?) rudimentary rays; scales more than 118; gill 

 rakers x+17; branchiostcgals 7; body cavity length measured from 

 snout less than a third of total length.
