Aglaja felis from the Bahamas

Bill,
Another little mystery....
I found these with the other aglajids [Chelidonura hirundinina, C. berolina, and Philinopsis depicta] over a range of 100 miles in the Exumas chain of islands, Southern Bahamas, in depths from 2 feet to 10 feet. [January - March, 2003].
The black ones were 1/8 inch to about 1 inch long. The brownish ones [lower photo] were a little "longer and skinny". The one in the photo was about 1/4 inch long and was photographed in a dish.

I am not sure these two are the same species - I guess only a detailed study of the populations will sort that out. Marcus & Marcus (1970) described another species from Puerto Rico which they called Aglaja felis. The living animals were 8-12mm long, and the colour is described from photos as 'velvet black all over, or dark reddish brown'. Thompson (1977) reports numerous 4-7mm long specimens of the black colour form from Jamaica.
The upper photo fits the original description of A. felis. The original description does not mention lighter specks on the body so it is possible the brownish speckled animal is a second species. I guess this is something that only more work will sort out
