worm, he twice snared a large Guinotia, pulling it from the water 

 only to have it drop back into the pool. After the second time, the 

 crab disappeared into the deeper area of the pool. A short time later 

 a crab that was beUeved to be the same individual because of its 

 not-too-common pale color was observed on the opposite bank, 

 approximately 12 feet away. It was facing the observer with its 

 eyes erect, chelae gaping, and it remained motionless for some 10 

 minutes until the observer made a sudden move at which the crab 

 quickly crawled into the edge of the water, in clear view and just 

 barely beneath the surface. It remained there for some 15 minutes,

 It seems safe to assume that an error of documentation is indicated 

 by the lot of three specimens recorded by Rathbun (1905) as having 

 been collected in "Mexico" by Bocourt. The remaining 11 species 

 now recognized in Guinotia are known only from South America 

 (and Trinidad), and it is highly unlikely that G. dentata, which is 

 otherwise restricted to the central Lesser Antilles, could have a 

 discontinuous distribution of more than 1,500 miles (in the wrong 

 direction) .
