803. GUAVINA, r.leeker. 



Guavina, Bleeker, Esquisse d'mi Syst. Nat. Gobioid., 302, 1874 (guavina). 



This genus is allied to Eleotris, ditit'eriiig in having the post-temporal 

 bones little divergent, not inserted close together, the distance between 

 their insertions greater than the moderate interorbital space, or 3;^ in 

 length of head; top of skull little gibbous; lower pharyngeals narrower 

 than in Eleotris; preopercle without spine; scales very small, ctenoid, 

 about 110 in a longitudinal series. Vertebra^ 11 + 13; teeth moderate, 

 the outer series on lower jaw enlarged. Fresh waters of the West Indies 

 and Brazil. Two species known; Guavina hrasUiensis (Sauvage) from 

 Bahia, and the following. {Guavina, the Spanish name.) 



2519. (JUAVINA Gl'AVIXA (Cuvier & Valenciennes). 

 (Guarubaco; Guavina.) 



Head 3^ ; depth 4^ to .5^. D. VI, or VII-1. 10 ; A. I, 9 or 10. Body stontish, 

 oblong; mouth oblique; maxillary reaching opposite middle of eye, its 

 length 2i to 3^ in head. Lower jaw little projecting ; teeth in broad bands, 

 the outer ones on lower jaw enlarged. Scales on head embedded; those 

 on body very small, ctenoid on sides, cycloid on back and belly, 100 to 110 

 in a longitudinal scries. Isthmus very broad. Pectorals reaching to mid- 

 dle of spinous dorsal. Highest anal ray If in head. Post-temporals inserted 

 twice as far from occipital crest as in Eleotris jjisonis. Parietals ending 



* Types, 2 specimens in poor order, from Vera Cruz, 0.09 mm. long. Snout a little more 

 steep and convex than usual in Dormitator maeulatus. Head 3| in length ; depth SJ. Eye 

 4J in head. 1) VII, 9; A. 11 ; scales 31-11. Soft dorsal very high, with round lihick spots. 

 Caudal and anal plain. This seems to be insepaiable {Tom Dormitator nMciiUitiis. 



t We have the following note on the type of Klrntrh oniiidisijiinma: Type specimen in 

 fair conditi(m, 0.14 nun. long, from "Anierique ,M. 1 idieiiiU' .'" Head sleriden-r than in D. 

 maeulatus, and much depressed, its depth at tin <\is li-.s.s than its width, which is less 

 than that of body. Anterior profile almost concave, l^audal fin large: other tins mod- 

 erate. Dorsal VI, 9; anal I, 9; scales about 29-11. A few dusky spots on dorsal and anal. 

 According to Dr. Eigenmann, specimens of Dormitator maculatiiti from the Rio Grande 

 agree fairly with this type, and it is not likely that it is dilierent.
