 fathoms, 2 or more specimens*. Crab Ledge,

 and 7606 (2 specimens); likewise one speci- 

 men found off Kopeecon Point at Phalarope 

 station 66. Survey. 



Boltenia sp. undetermined. 



Considerable numbers of a beautiful Boltenia 

 have been dredged by the Survey and by vari- 

 ous other collectors at Crab Ledge, in 16 to 25 

 fathoms on bottoms of gravel and stones. Prof. 

 Ritter has been unable to determine with cer- 

 tainty the identity of this species. In the 

 notes which he has furnished us it is entered 

 as "Boltenia ovifera (L.) ? Boltenia burkhardti 

 Agassiz?"

Glandula sp. 



Verrill and Smith, 1873, p. 701, 502. 



Verrill records an undetermined species of this 

 genus from "Vineyard Sound and off Marthas 

 Vineyard, 10 to 20 fathoms, sand. " Thespeci- 

 mens were less than one-fifth of an inch in 

 diameter; "the integument was densely cov- 

 ered by rather coarse and very firmly adherent 

 grains of sand in several layers. ' '

 half of Vineyard Sound; occasionally met with 

 elsewhere in the Sound and in Buzzards Bay, 

 where it appears to be confined to the inshore

of sand, stones, and gravel. Survey. Large 

 clusters of this species, sometimes associated 

 with Molgula manhatlensis , Perophora viridis, 

 Didemnum lutarium, and various hydroids, 

 Bryozoa, and algae, were not infrequently 

 brought up in the dredge. It is common, also 

 as a littoral species, being recorded from the 

 stone wall of the local pier, Vineyard Haven 

 and Edgartown, on piles, Nobska Point, and 

 Katama Bay.

 Woods Hole Harbor upon suitable objects. On 

 January 4, 1908, Mr. V. N. Edwards took great 

 numbers from a "cod car " anchored at the Bu-

 equal abundance upon the " cars " throughout 

 the summer of 1909. One or more specimens 

 were collected by Dr. Osburn at Vineyard 

 Haven, on piles July 31, 1906*. Mr. G. M.Gray
