20 OCTOPODID. 
Crsropus, Gray, 1849. 
Distr.—Only two species known; Celebes, India, Patagonia. 
C. Indicus, Ruppell (xxiii, 6). 
Body without fins; arms with two rows of sessile suckers ; 
upon the web connecting the arms is a bag opening by a small 
pore between each pair of arms. 
Sczureus, Troschel, 1857. 
Distr.—Two species; Mediterranean Sea. 
Body oval, wider than the head; arms short; cups or suckers 
with narrow bases. Third left arm hectocotylized. 
As the principal character on which this genus is founded, is 
the hectocotylized arm of the male, it is sometimes impossible to 
ascertain whether specimens belong to this genus or to Octopus. 
It is very probable that some of the species described under 
Octopus should be placed here. 
Atxoposus, Verrill, 1880. 
Distr.—A. mollis, Verrill (xxiv,13). 100m.8. of Newport, R.I. 
Allied to Philonexis and Tremoctopus. Body thick and soft, 
smooth; arms united by a web nearly to the ends; suckers in 
two rows, sessile; mantle firmly united to head by a ventral and 
two lateral commissures and by a broad dorsal band; siphon 
short, well forward. Right arm of third pair hectocotylized in 
the male, and developed in a sac in front of the right eye. 
Prinnocropus, Orb., 1845. 
Finned Octopus. 
Distr.—P. cordiformis, d’Orb. (xxiv, 12). New Zealand. 
Body like Octopus but finned ; arms with two rows of suckers. 
ELEpONE, Leach, 1817. 
Syn.—Polypus, Owen. Moschites, Schneider, 1784. Ozzena, 
Raf., 1814. 
Distr.—Three species; Norway, Britain, Mediterranean Sea. 
KE. Aldrovandi, Chiaje (xxiv, 11). 
Body rounded, without fins; the arms with a single row of 
suckers. Third right arm hectocotylized. f 
E. moschatus inhabits from 10 to 100 metres in depth, rocky as 
well as sandy shores of the Mediterranean Sea; it appears in the 
markets of Genoa in quantities from September to May. It is 
able to throw itself out of the water to a distance of 8 or 10 feet, 
and can also eject water from its funnel for over a foot. Verany 
has seen it repeat this jet eight times, taking six to eight respi- 
rations between each jet. 
Notwithstanding its musky odor, this species is largely used 
for food ; some skin it, and others use seasoning to diminish this
