Furthermore, the collection contains a specimen from the South 

 Pacific : 



Lat. 33° S.; long. 120° 57' W. U. S. S. WacJiusett, July 24, 1888. 

 Dr. W. H. Jones, United States Navy. ' 



Finally, the Albatross has taken the species at the Hawaiian Islands : 



Sta, 3808. March 23, 1902. Lat, 22° 10' N.; long. 155° 35' 45" 

 W. 50-0 fathoms. 9 specimens. 



The tube, with these nine specimens, contains the original label of 

 the Albatross, and, according to another label, Ortmann deter- 

 mined the animals as T. obtusifrons G. O. Sars; that they do not 

 belong to the last-named species, but to T. sequalis H. J. Hansen, 

 may easily be seen from the shape of the lobe on the first anten- 

 nular joint; but in the paper on the Hawaiian Schizopods Ortmann 

 wrote that he had seen five specimens of T. obtusifrons from station 

 3806 and 13 specimens from station 3888. The latitude and longi- 

 tude given for the last-named station show that 3888 is a misprint 

 for 3808; the animals from station 3806 are not in the collection. 



Distribution. — This species is widely distributed in the Atlantic, 

 the Indian, and the Pacific Oceans, as shown in my Harvard paper; 1 

 a goodly number of localities in the Indian Ocean are enumerated by 

 Tattersall in 1912. 2

 4, p. 218, pi. 5, figs, la-lm (with synonymy). 



Occurrence. — The Albatross has taken a single specimen in the Gulf 

 of Mexico : 



Sta. 2393. March 13, 1885. Lat. 28° 43' N.; long. 87° 14' 30" 

 W. 525 fathoms. 1 specimen. 



The specimen is a fine male measuring 39 mm. in length. 



Distribution. — It has been given in the Harvard work. According 

 to Tattersall (in 1912), it has also been taken at two stations in 

 the Indian Ocean.
