Albatross 2877, lat. 48° 33' N.; long. 124° 53' W. (coast of Wash- 

 ington), 59 fathoms, bk. s. m., September 25, 1888, 2 specimens. 



Albatross 3052, lat. 44° N.; long. 124° 57' W. (coast of Oregon), 48 

 fathoms, co. brk. sh. rky., June 8, 1889, 1 specimen. 



Albatross 3088, lat. 44° 28' N.; long. 124° 25' 30" W. (coast of 

 Oregon), 46 fathoms, c. p., September 3, 1889, 5 specimens. 



A bottle with half a dozen specimens, no label. The unlabeled 

 bottle is particularly unfortunate, since it contains the largest speci- 

 mens of the collection, one being 8.5 cm. by 5.5 cm. Another is so 

 much elongated fore-and-aft as to make it almost pedunculated, 

 though the posterior part is but little narrower than the anterior. 



HALOCYNXraA JOHNSONI Ritter. 



Ealocynihia johnsoni Ritter, 1909, pp. 65-98, pis. 7-14, figs. J-17 excepting 9 

 and 10. 



There are 5 very poorly preserved specimens of tliis species taken 

 in San Diego Bay by the Albatross, March 21, 1894. 



I am now adding to the United States National Museum collection 

 10 specimens from San Diego Bay taken from piles during the sum- 

 mer (July or August) 1911.

(This synonymy covers only names that have been used consider- 

 ably in the literature and those which have been recently proposed. 

 For fuller lists see Hartmeyer, 1903, and Van Name, 1912.) 



Hartmeyer has done a good service in bringing something of order 

 out of the chaotic state into which knowledge of +lus widely dis- 

 tributed, rather variable, and long-known group of ascidians had 

 fallen. But it is significant of the diversity of character and deceit- 

 fulness, as one might say, of the animals that, after having shown the 

 untenability of many of the hitherto recognized species, he should 

 have been led to establish still another that will have to be assigned 

 to the list of synonyms. We shall see presently that his B. thomsoni 

 can not be accepted.
