Two males, two female adults and two immature females of 
this form are present in the collection, all from Barbados, the 
nymphs in May, the day not indicated, the two males and one 
female on May 16 and the other female on June 14. 
One of the males is of the brown color phase and tends strong- 
ly towards the variety fusco-striatus of Redtenbacher. 
There is no doubt in the mind of the writer that this is a 
variety of the triops complex. Triops, with its synonyms mezt- 
cana, obtusus and dissimilis, has the vertex blackish beneath at 
the apex, as has also the color-form fusco-striatus; this ventro- 
apical darkening of the vertex fades gradually, as easily observed 
when a series of specimens are studied, to a wholly unicolorous 
vertex. Specimens in which the vertex is without ventro-apical 
infuseation are determinable as macropterus and occur in both 
green and brown phases of coloration. 
Contiguus Walker is a recorded synonym of mexicana, which 
is a synonym of triops, and it is almost certain that several other 
names in this genus will eventually be found to be synonymous 
with triops or some of its varieties.
