209. Calamus brachysomus (f.mkinglon). 

 Chrysophrys calamus GOnthkr, 1869, p. 421 (Paiiiiiiia). 



Known from the OJnlf of Culifornia, from Piinama, iiiul frotn S;mt;i Ilcltiia 

 Bay, near CJuaya.iuil (Boiiloiiger, 1808-0, Vol. XIV, p. 7). 



Several small specimens wore seen in llie market and a niinilier of larj^o 

 indiviihials were taken by the aid of dynamite about the islands. Four specimens 

 were preserved, ranging in length from 23 to 43 cm. 



Its southern representative, C. (aurinus, is a more slender species and has 

 shorter dorsal spines and a shorter pectoral. Two specimens of lamiiim which we 

 have examiiuHl from the (ialapagos are darker in color, especially about tlu; head, 

 and have the inner base of the pectoral blackish. 



The original description of C. brachysomus contains numerous errors and can- 

 not be relied upon. To the description given by Jordan and l'"vcrmann (ISOS, 

 p. 145;*), we make the following additions: 



Head 3.^ to 3.', in length; depth 2 to 2',. Eye S'i, to 44 in head; snout 1;;! to 

 1 J. The maxillary reaches to below the anterior orbital riiu. 'i'hore are but five very 

 small, short gill-rakers on the lower branchial arch. In our specimens, the dorsal is 

 constantly XII, 12 and the anal III, 10. The third dorsal spine is contained 1^ to 

 2: times in the head; the second anal spine is generally longer than the third, but 

 does not reach to its tip in the declined fin. Its length is 3^ to 4i in head.
