OPHIOLEPIDAE 



327 



Homalopliiura inornato, with similar short genital slits, it differs in the plates being much 

 thicker — there is even a slight indication of such thickenings as are so characteristic of 

 O. gelida — besides other characters (cf. Fig. 42 a, b). (That the species inornata is 

 referred to the genus Homolophhira while the present species is referred to the genus 

 Ophiurolepis does not mean that they are essentially different , since the genus Homalophhira 

 probably cannot be maintained as distinct from Ophiurolepis, see below, p. 329.) 



On the whole, I think the only possible course is to regard the specimen described 

 above as representing a separate species.
