Mr. Lyman's species : in fact, they belong to a different 

 genus, — Ophiopeza, — being without supplementary mouth- 

 shields, and having but two genital openings to each inter- 

 brachial space. I have collected a number of specimens 

 belonging to this genus near Wellington, among seaweeds on 

 the rocks, a little below low-water mark. These I at first 

 mistook for specimens of a new species, but I find by com- 

 paring them with the type specimens of 0. cylindrica, that 

 they are small individuals of that form. 



Ophiothrix coerulea, Hutton. 



This species was described by Professor Hutton from 

 specimens in the Colonial Museum. He subsequently found, 

 however, that they had been brought with a number of other 

 natural-history specimens from Fiji. This species must there- 

 fore be omitted from our list. 



Ophiomyxa australis, Liitken. 



This species is not uncommon on the rocky parts of the 

 coast near Wellington, in shallow water, among the roots of 

 Laminarians. There are also two specimens in the Colonial 

 Museum from Dunedin. It has been collected by Mr. H. B. 

 Kirk at Stewart Island. 



Asterina regularis, Verrill. 



This cushion-star is the commonest New Zealand As- 

 teroid. It is abundant on all the rocky parts of the coast 

 near low-water mark, and numerous in rock-pools, and on 

 piles and sea-walls in the harbours. This species varies much 

 in colour, form, and size. Greenish-grey varieties are perhaps 

 the commonest, although yellow, orange, purple, and dull- 

 green variegated with yellow are also abundant ; dark-purple 

 and many shades of blue frequently occur. In some speci- 

 mens the five rays are more prominent than in others. I 

 found two specimens at Ohiro Bay with six rays each, and 

 one of them had two madreporiform plates. It also occurs 

 on the east coast of Australia, but appears to be rare there, 

 the common form being an allied species {A. gunnii). 



Stegnaster inflatus, Hutton. 



This appears to be rather a rare species. I have found 

 one specimen at Ohiro Bay, attached to the underside of a 

 stone in a rock-pool. It is smaller than the type in the 

 Colonial Museum ; it is, however, brilliantly coloured and 

 handsomely marked, being rich orange above spotted with 

 deep dull-red and dark-grey, and white variegated with 

 reddish-orange beneath. There is a specimen in the Canter-
