Haz. Central America, at Realejo, in Nicaragua. 
CornEOT. University of Copenhagen (one specimen). 
This species never having been figured, I had a drawing made of it 
during my stay at Copenhagen. The only known specimen of this 
species, the one at Copenhagen, is considerably worn and nearly col- 
orless.

During an examination I was making (1872) of the collection of the 
University of Copenhagen, I discovered a Velorita, which I was able to 
identify as the adult of a species (parvula) which I had described from 
the young only. There were three specimens in the University, one of 
which was very kindly presented to me. 
The parvula, compared with Cochinensis, is very much less ponderous 
Velorita Cochinensis. 
and less trigonal; it is larger than Cyprinoides, but less ponderous and 
less trigonal. The hinge of my’ species is much narrower and less solid 
than that of either Oochinensis or Cyprinoides.
