Myra darnleyensis   Haswell  1879 (Crab)
Organism information awaits expert curation
Class: Malacostraca

Side wall of hepatic regions convex, not distinctly facetted in the adult; lateral margins of the carapace full, and not defined by any beaded line. Armature of the posterior margin consisting of three petaloid lobules. Fingers longer than the hand.

Carapace sub-piriform, globous dorsally, the lateral margins full and inflated and not defined by any beaded line. The three processes on the posterior margin are not spines, but broadly-laminar petaloid lobes. The front is prominent, but the dentiform ends of the walls of the branchial canals can be seen beyond it in a dorsal view. Behind front, the side-wall of the hepatic regions is full and convex, not flattened and distinctly faceted as it is in other species. The external maxillipeds are granular and hairy distally, being alike in both sexes. The chelipeds are alike in both sexes and are about twice the length of the carapace. The hand is short, about one third the length of the carapace (without spine). Fingers are markedly longer than the hand, the dactylus being about half again as the outer border of the hand.

In many adult females, as in most young, there is in the middle of the carapace a cruciform constellation of 5 enlarged bead-like granules or denticles.
