 L. spatula by the presence of numerous dark spots on the anterior part of its body 

 and head, but it is distinguished from L. oculatus primarily by its lack of plates on the 

 ventral surface of the isthmus, by its wider snout, and by the wider lower jaws.

 mens, 157. 0-416.0 mm length; from peninsular Florida.
