Dear Paul;-
Thank you for your comments. L. fritchi is a spineless variety, about
18mm (3/4 in.) with a sort of rosy pink-orange hue.
The L. sertata, on the other hand is pure Latiaxis. it is 42 mm long,
ivory white, with spines sticking out all over the place. The perc is
very thin and spirally striate.
