492 DR. R. O. CUNNINGHAM ON THE REPTILES, 
11. PIRIMELA DENTICULATA, Montagu. 
A specimen was obtained at St. Vincent, Cape-Verdes. 
12. PLATYONYCHUS PURPUREUS, Dana. 
This large swimming-crab is common at Coquimbo and in Luco Bay; and I have reason 
to believe that it extends along the west coast of South America as far north as Panama. 
13. LUPA SPINIMANA, Leach. 
This handsome species appears to be common at Rio de Janeiro, as it is frequently 
exposed for sale in the market. A fine specimen was taken on the rocks of a small 
island in the harbour in October 1866. 
14. Lupa RUBRA, Lam. 
Several specimens of this crab were taken on the rocks of a small island in the harbour 
of Rio de Janeiro in August 1867. 
15. LUPA CRIBRARIA, Lam. 
I found a number of specimens of this prettily marked species on the sandy beach of 
Five-fathom Bay, Rio de Janeiro, in the beginning of October 1867. 
16. TRICHODACTYLUS QUADRATUS, Latr. 
This species is common in freshwater streams and damp places in their vicinity in the 
neighbourhood of Rio de Janeiro. On one occasion, in August 1867, on a rock at the 
side of a stream at Tijuca, I found a female with between fifty and sixty live young ones 
under the pleon in the ordinary situation of the ova, which renders it probable that in this 
species, as in the Land-crabs, the young undergo no metamorphosis. Dr. Von Martens is 
right in his conjecture in the * Zoological Record” for 1868, that the crab which Mr. 
Spence-Bate has named Uca Cunningham is only this well-known species. 
17. TRICHODACTYLUS GRANARIUS, Nic. 
This crab (which, I think there is some reason to doubt, is not a true Trichodactylus) 
is common on the coast of South Chili. I generally met with it in situations where the 
sea-water was rendered brackish by small streams debouching into it. It was extremely 
common at Ancud (Chiloe); and I met with a single specimen at Port Laguna, to the north 
of the Darwin Channel, in the Chonos archipelago. 
18. PINNOTHERES TRANSVERSALIS, Edw. and Luc. 
A single specimen of this remarkable species was taken on the sandy beach near Punta 
Arenas (Sandy Point), in the Strait of Magellan, after a severe gale, in June 1867. 
19. HALICARCINUS PLANATUS (Fabr.), White. : 
This curious flat-backed crab is very common under stones on the beach at Punta : 
| nas and many other localities in the Strait of Magellan, where it was also dredged at 
- depths of from 12 to 15 fathoms. — ic E
