NOTE ON SELASPHORUS TORRIDUS SALVIN. 

 By ROBEKT RIDGI^VAY. 



By an error of identiflcation this species is given as 8. flamimda in 

 Mr. Nutting's catalogue of birds obtained on the Volcan de Irazu, 

 Costa Eica (cf. these "Proceedings," vol. 5, p. 497). The National Mu- 

 seum has obtained additional specimens of S. torridus from Costa Eica, 

 through Dr. Van Patten, and also of S. ardens, both species being ad- 

 ditions to the fauna of that country. 



S. fammula is as yet unrepresented in the National Museum collec- 

 tion.

A REVIEW OF THE SPECIES OF THE GENUS CALAMUS. 

 By DAVID Ji». JORDAIV and CHAKL.E:S H. OIIiBERT. 



In a recent visit to Key West and Havana Professor Jordan has col- 

 lected a large number of specimens of the genus Calamus, representing 

 five species. In attempting to identify these we have had many difii- 

 culties, owing to the scanty and miserable character of most of the lit- 

 erature pertaining to the subject. We have here redescribed the five 

 species mentioned above, and have attempted to collate the synonymy 

 of these as well as that of the remaining species.* Those features com- 

 mon to all known species of Calamus are not repeated in the descrip- 

 tions. A series of specimens representing each of these species is in 

 the United States National Museum. 



The following is an analysis of the five species obtained at Key West: 



a. Scales comparatively small, about 55 in the course of the lateral line. 

 i. Ui^per jaw with two strong canines directed forwards; body deep, the depth 

 about half the length ; preorbital with horizontal wavy blue lines. 



Pennatula, 1. 

 &&. Upper jaw without antrorse canines, 

 c. Anterior canines scarcely enlarged, about two to four in number in each jaw; 

 body deep, the depth about half the length; cheeks bluish, with roundish 



bronze spots C alajixjs, 2. 



cc. Anterior canines strong, about 6 in number in each jaw; body rather oblong, 



the depth 2f in length ; cheeks plain Bajonado, 3. 



aa. Scales comparatively large, about 46 in the lateral line; anterior teeth rather 

 small, uniform. 

 d. Dorsal outline forming a comparatively regular arch, the back elevated; 

 depth about 2 in length ; ventrals dusky ; a small, ink-like spot above base 



of pectoral Milneri, 6. 



dd. Dorsal outline not forming a regular arch, the profile of the head being very 

 convex, the back straightish ; body rather elongate, the depth loss than half 

 length; preorbital usually bluish, with bronze spots and dashes; no black 

 spot at base of pectoral above ; ventrals pale Akctifeons, 9. 



* Chryaophrijs taurinus Jenyns {=^Pagellvs cyanopterus Val.), from the Galapagos Isl- 

 ands, is omitted, as we are not sure that it belongs to this genus.
