CYMOPOLIA VERSUS PALICUS. 



In 1897 (Proc. Biol. Soc. Washington, vol. 11, p. 93), I replaced the 

 crab genus Cymopolia Roux (Crustaces de la Mediterranee, 1828, p. [77] ; 

 type, C. caronii Roux, 1828) with Palicus Philippi (Zweiter Jahresber. 

 d. Vereins f. Naturk. in Cassel, 1838, p. 11; type, P. granulatus Philippi, 

 1838 = C. caronii Roux, 1828), because the name Cymopolia had been 

 used in 1816 by Lamouroux (Histoire des polypiers corallig^nes flexibles, 

 1816, p. 292) for a genus of polyps. I did not then know that 

 Lamouroux' s genus though classed by him with the polyps is in reality 

 an alga. 



As the same name may be used for two genera in different kingdoms, 

 Cymopolia is tenable for a crab as well as an alga. The name Cymopolia 

 Roux is therefore restored and the family of which it is the type will be 

 known as Cymopoliidse. — Mary J. Rathbun. 



NOTES ON SEVERAL PREOCCUPIED GENERIC NAMES (AVES). 



Stenopsis Cassin, 1851, for a genus of neotropical Caprimulgidae, is 

 preoccupied by Stenopsis Rafinesque, 1815 (Analyse, p. 113), a genus of 

 Coleoptera. It may be renamed Thermochalcis * (type, Caprimulgus 

 cayennensis Gmelin). 



Oreomyias Berlepsch, 1907, a genus of Tyrannidfe, is not available, 

 owing to the prior Oreomyias of Reichenow, 1902, a genus of Musci- 

 capidse. For the former I propose to substitute Oreotriccus i- (type, 

 Pogonotriccus plumbeiceps Lawrence). 



Oreospiza Ridgway, 1896, a genus of Fringillidse of North America, is 

 long antedated by Oreospiza Keitel, 1857, for an Old World group in the 

 same family. The later genus is here renamed Oberholseria + (type, 

 Fringilla chlorura Audubon). 



Lamprotes Swainson, 1837, a genus of Tangaridae, is invalidated by 

 Lamprotes " R. L.," 1817, proposed in Lepidoptera. As Swainson's 

 genus appears to have no available synonym, I suggest for it 

 Compsothraupis § (type, Tanagra Joricata Lichtenstein). 



Odontorhynchus Pelzeln, 1868, a genus of Troglodytidse, is preoccupied 

 by Odontorynchus Leach, 1830, for a genus of Crustacea. It may be 

 called Odontorchilus II (type, Odontorhynchus cinereus Pelzeln).
