Eemarks. — But one recent specimen, with a number in a fossil state, were 

 collected by M. Voy and kindly placed in my hands. The granulated surface 

 is confined to the epidermis, and the summit of many of the granules is marked 

 with a cicatrix indicating a hirsute character. The nearest allied species is 

 H Dupetit-Thouarsi, from which it differs in its more depressed form and sur- 

 face structure. It is dedicated to Wm. Hillebrand, M.D., of Honolulu, a well- 

 known naturalist.
