AGONIDiE. 



35. Peristedium miniatum, Goode. 



Ferisicdiiim miinatHm, GooDE, Proc. U. S.Nat. Mus. iii, 1880, p. 349. 



Specimens were obtained from the following localities : 



Fathoms. 



No. 26023, station 86!) 192 



No. 26030, station 871 115 



No. 2H083, station 87() 120 



As has already been stated, adults and young were found, the former 

 full of nearly ripe eggs. 



36. Asphidophoroides monopterygius (Blocli) Valencjennes. 



In 1874 a head of an individual of this species was dredged up on the 

 " Pecten Ground" off Watch Hill, K. 1. This is the sole instance of its 

 capture south of Cape Cod, though there can be little doubt that it is 

 of frequent occurrence in the districts recently explored by the Coiiiuiis- 

 sion. 



37. Sebastes marinus, Linnaus. 



Numerous small individuals of this species were taken in nearly every 

 haul of the trawl-net down to the depth of 155 fathoms. 



38. Setarches parmatus, now species. 



A single specimen, No. 28084, was obtained at locality 87(5, in 120 

 120 fathoms. The young lish, 52'""' long, was taken in company with 

 inimerous young specimens of ISehastes marimis^ from which it differs in 

 many very striking respects. 



It appears to belong to the type described by Johnson under the 

 name Setarches.* 



It is, however, much stouter and higher than the other known spe(5ies 

 of this genus, Setarches GUntheri, from Avhich, too, it <liffers in having 10 

 instead of 11 spines in the lirst dorsal, and instend of 5 rays in the 

 ventrals. The height of the body (38) is three-eighths of its standard 

 length. The length of the head (45) is jiine-twentieths of the same. 

 The diameter of the eye (12) is contained less than four times in the 

 length of the head (45). The scales are small, cycloid, each with sev- 

 eral concentric furrows. 



The specimen is so young, and luutilated withal, that it seems scarcely 

 desirable to prepare an elaborate specihc diagnosis. I ai)pend, however, 

 a table of measurements, from which the other i^roportions of the body 

 may readily be deduced, hoping soon to secure materials for a better de- 

 scription. Setarches parmatus may readily be distinguished from Sebastes 

 marmus by its more generous proportions, as well as by the generic char- 

 acters already mentioned. The height of the hoCiy is three-eighths of
