the lower jaw plates differ so widely, but I do not know to what extent these are liable 

 to vary within the species. 



Among these specimens there are five preserved in their tubes : the latter are ro und 

 in section and have a thick layer of mud overlying the tough parchmenty basis. Inside 

 one of these tubes were a number of young specimens together with the parent : these 

 specimens measure about 15 mm. by i mm., and are at a much later stage of development 

 than the post-larval Diopatra ciiprea described by Monro (1924, p. 193). They were not 

 very well preserved within the tube, but as far as I can discover, they do not differ from 

 the adult form except in size. Augener (1918, p. 354) regards this species as identical

with D. ciiprea. I can only say that in the examples of the latter species examined by 

 me the relative length of the occipital tentacles and the number of rings to their 

 ceratophores seem to be constantly greater than in Ehlers' species. Ehlers' specimens 

 came from 35° 19' S, 20° 15' E.

Remarks. Two small specimens incomplete posteriorly: the larger measures 10 mm.

There are no tentacular cirri. The ventral cirrus and the cirriform prolongation of 

 the posterior lip of the chaeta sac disappear by the 4th chaetiger. The pseudo-compound
