parvi, haud prominentibus ; pupillo nigro ; iride argentato: apertura 
lata: os parvum, eccentricum : umbella parva: brachii graciles, atte- 
nuati, pro longitudine 2, 4, 3, 1, supertoribus robustis, alteris grada- 
tim gracilioribus ; acetabulis numerosissimis, confertissimis : tunica 
reticulato-papillosa, areolis pallidis ovalibus signata ; supra auran- 
tiaca, strigis longitudinalibus flavidis quinque, et maculis alternantibus 
etiam intra-brachialibus variegata. 
Body subglobose, the length exceeding the breadth about one-twelfth. 
Head two-thirds as long as the body, and about half its breadth, of 
nearly equal width throughout, the eyes being but very slightly pro- 
minent. Inferior opening broad, the lip transverse and simple; eyes 
small, the pupil black, with a silvery iris. Mouth small, situated at the 
lower third of the umbrella, which is rather small, but well-marked, the 
membrane not prolonged up the arms. Arms compressed, long and 
slender, attenuated to a thread, comparative length 2, 4, 3, I, differing 
much in size, the upper ones being very robust, the second, third, and 
fourth pairs being successively more slender, the latter being remarka- 
bly slender, not half the size of the upper ones. Cupules of medium 
size, nearly sessile, crowded, very numerous, extending to the tips of 
the arms; they commence in a double series on the upper arms, while 
on the lower ones the first six are in a single series. The surface is 
coarsely reticulate-papillose, with a series of oblong-oval, smooth, and 
colourless patches along the back of the arms and around the sac, 
somewhat resembling bullae. The ground colour is deep orange ; be- 
neath somewhat clouded with white; above variegated with five lon- 
gitudinal, buff stripes, the median one extending to between the eyes, 
the two lateral ones curving on each side, like meridian lines, and ex- 
tending only to the neck; between these lines, arou nd the middle of 
the sac, are deep brown patches, and also between the bases of the 
arms; there are also brown mottlings along the back of the arms. These, 
with the pale, bubble-like patches around the base of the sac and along 
the arms, give a very gay and diversified colouring. 
Length of sac to inferior opening, one and a half inches; length 
along the back to the umbrella, two and a half inches; breadth of sac, 
one and three-fourths inches; breadth of neck one inch; breadth of 
umbrella from side to side, three inches; breadth above mouth, two 
inches; below mouth, one inch; length of arms, upper pair, twenty
