These examples were contained in the same bottle as the young of Selenocosmia 
javanensis, the female being by no means easy to distinguish from them. In S. javanensis 
however, the carapace is considerably longer as compared to its width, this plate for example 
measuring in one specimen 8 mm long and 6.6 mm in width; the anterior legs, moreover, 
are more robust and the tarsal and protarsal scopulae thicker. 
This genus Phlogiellus is little else than a Selenocosmia that has retained certain 
primitive features such as the inferior claw on the 4 ®® leg and the divisional line of setae 
on the tarsal scopulae, resembling in these respects the young of S. javanensis. The genus 
thus affords a good illustration of the biological law that with two closely allied species, the one 
in which the individuals are of much smaller size than are the individuals of the other, 
retains certain features in the adult which are characteristic of the young of the second. A 
parallel case is furnished by the two existing species of Hippopotamus, namely amphibius and 
liberiensis.
