Abundant at Stations 2 and 3. and rare at Station 0. As its name implies, 

 this species is exceedingly variable, and the series from Stations 2 and 3 cover 

 practically the whole gamut of variations. The specimens range between thin 

 regular spineless forms. Ihiclcer spineless forms practically inseparable from A. 

 romiiald. normal spinous individuals in whicli the regular development of the 

 shell is iu)t !o.st, and wild-growing .specimens with abnormal development of the 

 spines and sometimes with accessory chambers. Even the development of 

 the spines does not follow any fixed line, for, in some instances, they are developed 

 from the ends of the strongly limbate sutures and are formed of solid shell- 

 matter, while in others they are developed from the wall of the chandlers, 

 occasionally with an aperture at the tip. The development of these particular 

 forms may be observed in the case of shells which have lived sessile upon large 

 sponge-spicules. The surface availal)le for attachment being small, relatively to 

 the size of the organism, an extension of the chamber is seen to l)e launched 

 out in each direction in the axis of the spicule. Similar .specimens have been 

 admirably figured by Chapman (C. ini»l. FLC. p. 3i)2. ])1. 1).

Extremely rare. The scarcity of this species, as compared with the abundance 

 of A. pnh/morpha occurring at the same Stations, is very noticeable.
