46 NOTES. 
STRONGYLOCENTROTUS TUBERCULATUS. 
This fine Urchin, which attains a considerable size, is very 
common at Lord Howe’s Island. I have not met with any from 
the. mainland. The spines are long, strong, sharp, and solid, 
finely striated longitudinally ; on the ambitus and below the 
shafts they are distinctly flattened, and in color of a uniform rich 
olive or olive brown, although finely striated they feel smooth 
and polished ; the flattened spines are more numerous and 
distinct in the young than inthe adult. I can find no description 
of the spines of this species in any work at my disposal. The 
test closely resembles that of 9. franciscanus, but the porriferous 
zone is not so petaloid on the actinostome ; the spines in spirit 
specimens are often of an olive-yellow color. 
STRONGYLOCENTROTUS ERYTHROGRAMMUS. 
This species is very plentiful in Port Jackson, and may be 
found between the tides at almost any time, it is also 
occasionally dredged in 10 to 20 fathoms. In color the spines 
vary from rich purple to pale brown or cream color. It 
seems to attain to a greater size to the South, especially in 
Tasmanian Waters The tests vary considerably in height, some 
being only one-third of their diameter. From the coast near 
Newcastle we have received some large specimens, measuring 
three and four inches across and 1°5 in height They are in 
habit gregarious, a dozen or more may be found clustered round 
one stone. They are seldom found on the sandy flats, and the 
few dredged there are always of small size; occasionally 
malformed tests are found. 
SPHARECHINUS AUSTRALIA. 
Taken on sandy bottoms in 5 to 10 fathoms, sometimes close 
to the shore, comparatively rare on’ the Australian Coast. 
Mr. Tentson-Woobps states that it is found in Bass’ Straits, 
King’s Island, and Tasmania. Mr. Morron obtained specimens 
in the Solomon Islands. 
TEMNOPLEURUS TOREUMATICUS. 
Although this species has been obtained both during the 
voyages of the “Chevert”’ and “Alert,” and also by our 
Assistant, Mr. Auex. Morron, on the Australian Coast, it is 
far from being common; a good series is still among the © 
desiderata of the Australian Museum. It is found on sandy | 
mud bottoms in from 5 to 20 fathoms.
