albula, and may, therefore, be suppressed. 
Page 405. The types of Atlierina Carolina C. & V., examined by us in' 
the Museum at Paris, show the following additional characters : 
A true Atlierina. Eye large, 2^ in head. Scales nearly or quite en- 
tire. Spinous dorsal wholly in advance of the vent. Ventral reaching 
past front of vent and dorsal nearly to it. Head 4^. Lat. 1. 52. 
Page 406. In LaMdesthes, the premaxillaries, though broadened be- 
hind, are much narrower than in Menidia, and but little broader than in 
Atlierina. 
Page 406. The date of the name 3Ienidia is apparently 1836.

Coast of ITorth Carolina. The synonymy given in the text (page 
407) belongs to No. 644. 
Page 407. In Menidia, vagrans the scales are all very firm, with rough 
edges. A. I, 15 to I, 18. Silvery band broad; back with lines of dots 
following the rows of scales; pectoral and caudal yellowish in life. Soft 
dorsal and anal scaly. Florida to Texas.

Color and form of M. notata; edges of scales somewhat dotted; a 
dusky streak at base of anal. Head rather broad and flat above. Mouth 
small. Eye 3 in head, equal to snout and to interorbital space. Vent 
a longitudinal slit, its length two-thirds diameter of eye. First dor- 
sal spine inserted immediately above anterior part of anal slit, slightly 
nearer base of caudal than snout. Pectorals extending to beyond bases 
of ventrals, their length four-fifths head. Ventrals reaching vent. In- 
terspace between dorsals twice diameter of eye. Top of head covered 
with large scales. Lateral silvery band on fifth row of scales and edges 
of fourth and sixth rows; the extreme parts of fifth row not included 
in it. Scales with entire edges, which are nearly straight, so that
