ANNOTATED LIST. 55 
Nardoa tuberculata. 
Gray. 1840. Ann. Mag. Nat. Hist., 6, p. 287.—Kochler. 1910. Indian Mus. Ast., pl. xvii, figs. 1, 2. 
The type locality for this species is Port of Sual, Luzon, Philippine Islands; it is known, 
however, not only from other points in the Philippines, but also from Ceylon, Java, Batjan, 
Flores, Amboina, Halmaheira, Timor, and Dutch New Guinea. Bell reports it from 
Cargados Carajos, western Indian Ocean, 30 fathoms; from northwestern Australia, 9 
to 38 fathoms; from Macclesfield Bank, 30 to 46 fathoms; Sandal Bay, Loyalty Islands; 
and from the Enganin Group, British New Guinea. He also records tuberculata from the 
Arafura and Banda Seas, but as he gives the definite locality as ‘‘Parry Shoal,’ which is 
on Macclesfield Bank, this record need cause no trouble. The species is one of the larger 
members of the genus, R reaching at least 130 mm. The color of this species is either 
unusually variable for a Nardoa or more than one species is included at present under the 
name tuberculata, for von Martens says the color in life is brown-yellow, with dark blood- 
red transverse bands, while Herklot’s colored plate shows a gray-brown ground-color 
with 4 or 5 broad, sharply defined, dark-gray bands across each arm. Sluiter and de Loriol 
say their specimens show no crossbands, and there is no hint of such bands on any of the 
specimens in the Museum of Comparative Zoélogy. There is great individual diversity 
in the size, number, and arrangement of the tubercles. Two specimens in the Museum of 
Comparative Zodlogy from Port Galera, Mindoro, Philippine Islands are notable because 
the tubercles are so low and broad; in typical specimens the tubercles are about 2 mm. 
in diameter at base and about 1.5 mm. high, but in these specimens they are 2 to 2.5 mm. in 
diameter and only 0.5 to 1 mm. high. 
Nardoa frianti. 
Koehler. 1910. Indian Mus. Ast., p. 158, pl. xvii, fig. 3, 4. 
A very well-marked species, taken at the Andaman Islands in 20 fathoms and recorded 
also from Tawi Tawi, Sulu Archipelago, in10fathoms. Thelargest specimen has R = 126mm. 
Nardoa tumulosa. 
Fisher. 1917. Proc. Biol. Soc. Wash., 30, p. 90. 
The Albatross took the type of this species in 12 fathoms off Tinakta Island, Tawi 
Tawi group, Sulu Archipelago, on a sandy bottom. R=about 90 mm. while r=about 14, 
so the rays are rather short for a Nardoa; they are also wider (17 mm. at base) relatively 
than in frianti. Fisher (1919) thinks it possible that this may be the adult of obtusa Perrier, 
which is based on a small Nardoa with R only 35 mm. 
GOMOPHIA. 
Gray. 1840. Ann Mag. Nat. Hist., 6, p. 286. 
Genotype: Gomophia egyptiaca Gray. Monotypic. 
Although Perrier and Sladen merged this genus in Scylaster and Nardoa respectively, 
it seems to me a mistake to ignore its unusual characters. While the conspicuous pointed 
tubercles serve best for the distinguishing character in an artificial key, as given above 
(p. 37), this feature is not of nearly so much importance as the reduction and irregularity 
of the superomarginal plates and the presence of a well-developed series of intermarginal 
plates on the basal part of the ray. All these characters combined warrant maintaining the 
genus quite apart from Nardoa. 
Gomophia egyptiaca. 
Gray. 1840. Ann. Mag. Nat. Hist., 6, p. 286—Koehler. 1910. Indian Mus. Ast., p. 157, pl. xvii, figs. 5, 6. 
This species has a wide distribution, ranging from Mauritius to Samoa. Sladen 
records it from the Hawaiian Islands; while this is probably a mistake, its occurrence there 
would not be strange. Koehler records a specimen in his collection, from Mindanao, which
