f 



the West Indian region as the ''Indian Seas." I do not think that 

 Professor H. Milne Edwards was in error, but that some present-day 

 writers have merely overlooked the above fact. 



Distribution : Known from shallow water to 50 fms., from Beau- 

 fort, N. C, southward, including the Bahamas, Bermudas, Florida, 

 the Gulf of Mexico, the West Indies down to Curacao ; also Brazil. 



Material examined : Two males and one female from Porto Padre, 

 Cuba, March 15, 1928. One male dredged in 50 fms., American Shoal 

 Light, Florida, March 3, 1924, establishing the greatest depth from 

 which this species has been taken. One male taken at Port Segua la 

 Grande, Cuba, in 3 fms., February 23, 1925. 



Color: In life this species is a deep sandy gray with a rose tinge 

 and with minute black flecks, resembling the sea-sands in which it 

 spends the greater part of its life buried, except for its eyes and 

 breathing apertures. 



Technical description: Carapace flattish, triangular, rostrum 

 short, prominent, consisting of a median tooth flanked on each side by 

 a smaller tooth; channelled on the upper surface; anterolateral mar- 

 gins rounded, protruding out into 7 or 8 serrate teeth; one strong, 

 outward pointing spine at the angle formed by the anterolateral and 

 postlateral margins ; the latter are wide, slightly convergent, arcuate. 

 The gastric and cardiac regions are elevated ; a deep pit on either side 

 marks the urogastric line; the branchial regions are well defined and 

 elevated. There are numerous tubercles and elevations on the upper 

 surface; five of the larger tubercles occur in the median line: two 

 gastric, two cardiac, one intestinal, this last being on the posterior 

 margin; on either side there are three large granules on the posterior 

 margin and running obliquely inward from this is a line of granules, 

 some of which are much larger than others. Beneath and below the 

 lateral spine there is a single spine-like tubercle opposite the base of 

 the first ambulatories. The pterygostomian and subhepatic regions 

 bear an excavation which reaches to the inferior external orbital mar- 

 gin, forming, with the assistance of the retracted chelipeds, covered 

 afferent passages, whose external apertures are between the base of 

 the finger and margin of the orbit. 



The antennae are very small. 



The antennulae are large and fold obliquely within the rostral 

 hood.
