OF NEW SOUTH WALES. 161 



One specimen of this species was dredged by the Chevert off 

 Darnley Island and others, have been found on the N". Queens- 

 land coast, though it is rare. Test when dry yellowish brown, 

 moderately thick, subglobular, and thickly covered with short- 

 pointed greenish spines, banded with five or six transverse bands 

 of violet. The spines below are much longer, broader, frequently 

 flattened. Actinosome moderate, decagonal, with slight indenta- 

 tions, anal system large. Pores at the median junction small, 

 horizontal sutures of the coronal plates slightly furrowed. Diam. 

 from 44 to 53 ; alt. from 27 to 35 mil. (Agass.) 



Salmacis rarispina, Agass. 



Test usually quite conical, much thinner than any other 

 species. The coronal plates above the ambitus are comparatively 

 bare, owing to the distance of the primary tubercles, and the 

 small number of the milliaries. The test above the ambitus is 

 greyish, with lozenge-shaped figures along the horizontal sutures. 

 Actinosome small, quite sunken, and almost circular. Spines, 

 long, slender, pointed, somewhat flattened, straw color, with seven 

 to eight bright purplish bands. Sutural pores quite minute. 

 Diam., 25 alt. 16 mil. Darnley Island and Cape York, a few 

 specimens dredged by the Chevert, at about twenty fathoms. 



Salmacis globator. Agass. 



Test quite stout. Tubercles remarkably uniform, and forming 

 very regular horizontal and vertical rows, slightly larger on the 

 actinal side. Porif. zone not so wide as other species, and the 

 sutures of the plates becoming in places deep furrows, almost as 

 marked as Temnopleurus. The spines (which easily fall off) are 

 short, stout, pointed, greenish and tipped with violet. Color oi 

 test pinkish, sutures lighter in color, yellowish below. Auricles 

 remarkably broad and thin, with high connecting ridge. Diam. 

 from 60 to 70 ; alt. 36 to 52 mil. Port Jackson, dredged off the 

 Sow and Pigs rocks, by Brazier, Bass's Straits, Kangaroo Island, 

 S. Australia. Not common, and rarely found with the spines 

 attached.
