Of the three specimens contained in the United States National 

 Museum,, one is hibeled Isle of France, Isaac Lea collection. The 

 others, without data, are rather remarkable for the wide spacing of 

 the annuli. That show^n in plate 05, figure 5, is 50 mm. long, 17i mm. 

 in greatest diameter. The series in the collection of the Academy of 

 Natural Sciences in Philadelphia is witliout locality. I do not know 

 that it has been found on any whale in North American waters. 

 Darw in gives the localities : Southern Pacific Ocean, western South 

 America, New South Wales, Cape of Good Hope. Gruvel, Marloch, 

 and Stebbing have given South African localities. It lives on the 

 southern right whale Balcena australis, on tlie upper jaw, forehead, 

 and over the eye. 



In the year 1650, specimens of Tuhicinella were observed on the 

 head of a whale found dead on the coast of S3aleroe, one of the Faroe 

 Islands, according to Doctor Olao Worm, who gives two character- 

 istic figures in liis Museum Wormianinn, page 281, published in 1655. 

 This is tlie only reference I have found to the occurrence of Tuhi- 

 cinella in the Northern Hemisphere.

It is described by Darwin as having " shell almost rudimentary, 

 star-formed, composed of six compartments; with a long peduncle- 

 formed bod}^ rising from the middle; opercular valves none." 



This animal has a striking superficial resemblance to Co?who- 

 derma {Otlon) aurltuni, wdiich is also found on cetacea, though 

 never attached directly to the skin. 



1 Mr. Stebbing has, in my opinion, taljen the first word of Lamarck's diagnosis for a 

 specific name. That the words inclosed in parentheses in Lamarck's paragraphs are the 

 real specific names is demonstrated by his following paragraph, where he says that 

 " Le eitoyen Fanjas * * * ,^'jj (jj^- q„g jp tuhicinella major a ete decouvert dans les 

 mers du sud de I'Amerique."
