NOTES ON GLOSSAMIA AND RELATED 

 GENERA OF CARDINAL FISHES. 



The genus Glossamia as Mr. Allan R. McCul- 

 loch (Records Australian Museum, February 20, 

 1917), has shown, is based on Apogon aprion Rich- 

 ardson, a species quite distinct from the American 

 species called Glossamia pandionis Goode & Bean. 



Glossamia has few and short gill rakers, 6 devel- 

 oped, and also a small patch of teeth on the tongue. 

 In the typical species the scales are small, 40 to 43. 

 In a second species, Glossamia gilli (Steindachner), 

 with which species the type of Mionurus Krefft (M. 

 lunatus), is identical, the scales are larger, 26 to 31. 

 In both the nape is depressed giving an S-shaped con- 

 tour to the region before the dorsal fin. 



The genus called Glossamia by Goode and Bean 

 (Oceanic Ichthyology, 1895, 231), may be known as 

 Xystramia Jordan, new genus, from its long and 

 numerous gill rakers (about 14). Its type is Glos- 

 samia pandionis Goode h Bean. 



The genera of small Apogonids having the pre- 

 opercle entire on both limbs have been much confused 

 by authors, not least by the present author. They 

 may be thus compared: 



a. Preopercle with both limbs entire; anal fin 

 short, its rays about II, 8, no canines. 



b. Palatines with teeth. 



c. Lateral line complete or very nearly so. 



d. Body much compressed and elevated; dorsal 

 spines produced; gill rakers long, slender, 

 6+21; scales large; caudal forked, (Mio- 

 nurus Jordan & Seale, Fishes Samoa, 1906, 

 247, not of Krefft, 1867), (type Apogon 

 graejfi Gunther) ; zoramia Jordan, new 

 genus. 



dd. Body not much compressed and elevated; 

 spinous dorsal low; caudal rounded or trun- 

 cate.
