Genus: CALIGUS Miiller. 

 Caligus aliuncus Wilson. 



Type: The type, a female, was taken at the surface with electric 

 light, by the ''Albatross/' without further locality, and is deposited 

 in the United States National Museum. 



Material examined : Seven specimens taken from the outer skin of 

 a dolphin, caught February 19, 1926, by the ''Ara." 



Distribution : Known only from the two records cited above. 



Remarks : The female has been fully described and figured by Dr. 

 C. B. "Wilson. The discovery of the male of the species, taken 

 for the first time by Mr. Vanderbilt, should prove of interest to future 

 workers. 



Mr. Vanderbilt 's field-notes state that this species is coral red in 

 color when fresh. I think that this red color may possibly be due to 

 the ingested blood from the host, showing through the skin. The color 

 pattern of the preserved adult specimens is dirty ocher, marked in 

 the median portion with a definite pattern in dull brown.
