482 DR. R. O. CUNNINGHAM ON THE REPTILES, 
13. TECTURA ZEBRINA, Less. 
This species was met with abundantly at Lota and Luco Bay. 
74. SIPHONARIA VENOSA, Reeve. 
I found this specimen at St. Vincent. 
15. SIPHONARIA MAGELLANICA, Ph. 
This species is very common in the Strait, abounding on the rounded stones on the 
beaches. 
CHITONIDA. 
76. CHITON ACULEATUS, Linn. 
I procured some magnificent specimens of this species on the rocks at Coquimbo. It 
is almost invariably to be met with in very exposed situations, on rocks on which the 
surf breaks violently; so that to obtain it involves a considerable amount of danger and 
difficulty. 
77. CHITON MAGNIFICUS, Desh. 
Fine specimens of this handsome species were met with at Coquimbo, generally in 
similar situations with the preceding, the difference being that the C. magnificus ap- 
peared to prefer clefts in the rocks. 
78. CHITON GRANOSUS, Reeve. 
This species I found at Chiloe, and also in the channels on the west coast of Pata- 
gonia. It does not appear to extend as far south as the Strait of Magellan. 
79. Curron Cuminent, Fremb. 
This beautiful Chiton was found at Coquimbo. 
80. CHITON ELEGANS, Fremb. 
This species was also met with at Coquimbo. 
81. CHITON CHILOENSIS, Sow. 
` This species is very common at Chiloe. It appears to me to come very near 
C. elegans. 
82. Carron BowEN11, King. 
I found a number of specimens of this species at Chiloe; but I do not remember 
observing it in the Strait of Magellan, where King appears to have procured it. 
89. CHITON SETIGER, King. 
This is much the commonest Chiton in the Strait of Magellan and western channels, 
and sometimes attains a considerable size. 1 have met with specimens 3 inches long. 
In old individuals the sculpturing of the valves is frequently much obliterated, and the 
fasciculi of setze are often worn off.
