Tlie species is common. I have met with it from low water mark 

 df)wn to twenty fathoms. There is no doubt in my mind that if 

 dolaJn-iferu was collected at a locality north of the equator, it 

 would be identified without hesitation as itihaerens. The only 

 slight, Init fairly constant difference, that 1 could detect, was in 

 the width of the anchor plates, which in dolahrifera are slightly 

 narrower. The calcareous ring may be quite without neural per- 

 forations, or it may have any number up to five. The colour may 

 vary from rose to white, and one specimen from Wilson's Promon- 

 tory was a deep purple black.

There is one specimen in the Museum collection. This was col- 

 lected by Mr. Kershaw, at Wilson's Promontory; it is very con- 

 siderably contracted, measuring 70 mm. by 15 mm., the integu- 

 ment being much wrinkled transversely, and quite opate. Mr. 

 Roebuck has twice met Avith the animal at Torquay. On the 

 last occasion he collected six specimens on a far outlying reef, 

 wliicli is exposed only on the occasion of an exceptionally low 

 tide. He gave me two excellent specimens, one of which, in spirits, 

 measures 15 cm. in length. Mr. Roebuck describes the animal in 

 life as being of very handsome appearance, bright scarlet in 

 colour, with dense, Avhite, prominent papilae. A large specimen 

 is capable of extending itself to a length of from eighteen inches 

 to two feet. When handled, they are very prone to separate them- 

 selves into two or three pieces. The description of Dendy and 

 Hindle (5) rendered the identification easy, but the difference of 

 the spacing of the radial muscles, noticed by these authors, cannot, 

 I think-, be regarded as a constant character.
