This species, together with Rh. sumatranus and calypso described below, form a small, well-marked section of the lepidus group, which might conveniently be termed the acuminatus section, confined to Java, Lombok, Sumatra, and Engano, and differing from all the foregoing species:- (1) in being very much larger ; Rh. lepidus is in size like a Rh. hipposiderus ; Rh. sumatranus like a small Rh. ferrum-equinum ; (2) in being a trifle more advanced in dentition: there seems to be no " vacillation" in the position of p3. Sella in Rh. acuminatus practically parallel-margined ; on very close examination an extremely faint indication of an expansion below the middle can be traced. Lancet strongly hastate.
