almost identical in structure in so many different species (PI. II. 

 Fig. 2). To be able to see the structure of these pedicellariae they 

 must be examined from the inner surface ; it is then seen that there 

 is only a single series of small teeth along the outer margin and 

 a few ones irregularly disposed below this series in the median 

 line. (PI. II. Fig. 1). Also the whole outline is quite different 

 from the common form, as seen by comparing the figures 1 

 and 2. In sideview this curious structure is not to be seen.

The specimens in hand must be referred to the Var. Gunneri^ 

 thoughnotbeing very marked. One of them, preserved in formaline, 

 has retained the red colour On the abactinal side very well. 

 The small specimen (R == 41 mm., r. = 17 mm,) looks rather 

 curious, the spines of the disc being well developed, whereas 

 pedicellariæ and papulae are as yet very scarce. There can be 

 no doubt, however, that it is the same species as the large 

 specimens. 



In this species the forcipiform pedicellariæ are even more 

 characteristic and unlike the common form than in A. panopla. 

 (PI. II. Fig. 3). The upper end of the valve is not at all widened, 

 ending in two large hooks and — mostly — a smaller one between 

 them. Below there is a continuous series of teeth along the 

 median line of the valve, a single series in the upper part, a 

 double series in the lower part; at the lower end of the valve 

 there is a larger group of teeth, as usually. This curious struc- 

 ture can only be rightly understood, when the valve is examined 

 from the inner surface. Danielssen&Koren, who have figured 

 the pedicellariæ in side-wiew only, therefore have failed to 

 understand it.
