Arr. XXIII. — Description (with figure) of Menobranchus 
punctatus. By Lewis R. Grepes, M. D., Prof. Math. 
Coll. Charleston, S. C. 
Ar the meeting of the American Association, at Charleston, 
in March, 1850, specimens and drawings of this species were 
exhibited, and a short notice of it given, (page 159 of Pro- 
ceedings.) Of the ten individuals that had been obtained at 
that date, one was dissected by myself, and one by Dr. St. Ju- 
lien Ravenel, one was accidentally lost, and the remainder 
preserved in alcohol. The examination of all the organs was 
not completed during the dissections, but the hope of obtain- 
ing additional specimens has not since been realized, and I 
am induced to offer the results of the examination, incomplete 
as they are, without further delaying the promised publication.
