the length of the rostral plate. In one large female of about 198 mm. in 

 median length, exclusive of the rostrum, the raptorial propodus was 

 shorter than the carapace exclusive of the rostrum. This specimen, by the 

 way, had, including the terminal one, 8 teeth on the left raptorial dactylus 

 and 13 on the right! 



I have never seen or heard of a specimen of L. scabricauda from other 

 than the east coast of America, from Florida to Brazil (except a small 

 postlarval specimen from the surface of Vineyard Sound, Massachusetts). 

 Balss^^ records its occurrence on the west coast of Africa at Toto Lome 

 and mentions also Sao Thome (Osorio) and Boutry (Guinea) (Herk- 

 lots), this last, however, with the comment that he could not find this 

 place on any chart. Thus, L. desaussureij its Pacific analogue, apparently, 

 for want of evidence to the contrary, must still be regarded as a distinct 

 species, even though the evidence in its favor is meager. H. J. Hansen^ ^ 

 believed desaussurei to be no more than a synonym of L. scabricauda. It 

 seems strange that no specimens of either have ever been turned up some- 

 where on the Pacific coast of America.

 Distribution: The unique male type was collected by L. Diguet in 

 the Bay of La Paz, Lower California. It was found living as a com- 

 mensal in the burrow of a Balanoglossus, along with a polynoid worm, 

 Lepidasthenia digueti Gravier.*^® The species apparently has never been 

 seen again since the original discovery, until taken by the Hancock Ex- 

 peditions, first in 1936, when a much broken, very immature male speci- 

 men, apparently in the so-called first littoral stage, was dredged on 

 March 16 in Puerto Escondido, west side of the Gulf of California, 90 

 to 100 miles north of the type locality (Hancock Exped. Sta. 595-36) ; 

 and again in 1938 on January 11, off San Jose Light, Guatemala, the 

 first female specimen (Hancock Exped. Sta. 770-38).
