Body elliptical, oblong, compressed; head conic; mouth small, oblique, 

 the lower jaw sliglitly shorter; lips thiu, the lower without frenum; teeth 

 small, conical, rather numerous, in 1 series. Gill rakers moderate, slender; 

 scales comparatively large; dorsal spines rather high, some of the middle 

 ones highest, the posterior not so high as the soft rays; the soft dorsal 

 shortened; anal moderate, with weak spines; caudal forked; pharyngeals 

 normal, the teeth mostly conic, the central and posterior teeth molar; 

 vertebrte 14-f-20=34. Carnivorous species of small size, abounding on 

 sandy or muddy shores, (nujiia, foetus; yadnjp, belly.) 



1882. CYMATOGASTER AGGREGATUS, Gibbons. 



(Sparada; Viviparous Perch.) 



Head 3i; depth 2|. D. IX, 20; A. Ill, 23; scales 3-38-11. Body elon- 

 gate-oval, compressed, heaviest at the front of the dorsal ; caudal pedun- 

 cle short aud slender; head short; teeth A^ery small, conical, -g- ; dorsal 

 spines high and rather feeble, rising rapidly to the fifth, thence slowly 

 descending, the last lower thau the soft rays; pectorals reaching past tips 

 of vcntrals, which do not reach nearly to vent; third anal spine the long- 

 est, shorter than soft rays; ventral spine situated about 2 scales behind 

 the vertical from the base of the pectoral. Cheeks with 3 rows of scales^ 

 Gill rakers short and slender, about 18 below angle. Silvery, back dusky ; 

 middle of sides anteriorly with the scales each with a cluster of dark 

 points, these forming a series of longitudinal stripes, which extend to 

 opposite the base of the anal; these stripes are interrupted by 3 vertical 

 light-yellow bars, on which are no black specks in the adult, t Adult 



*The name Oymatogaster wa.s first applied by Dr. Gibbons to 2 species, aggregate 

 and minimus. Shortly afterwards Dr. Gibbons transferred the name Oymatogaster to 

 Holconot^ls, giving a new name Micrometriis to aggregatus and minimus. Still later, 

 Girard gave the name Abeona to minimus and Agassiz gave the name Metrogaster to 

 aggregatus. In 1862 Gill restored the name Oymatogaster to aggregatus, an arrangement 

 which should probably stand.
