BULLETIN OF THE BUREAU OF FISHERIES. 



Lepralia pallasiatia Continued. 



Independent records for this species: Buzzards 

 Bay at repetitions (1909) of Fish Hawk sta- 

 tions 7645, 7648, and 7671, and of Phalarope 

 station 83; Woods Hole Harbor, on piles; 

 West Falmouth Harbor, shallow water; New 

 Bedford, on piles; Cedar Tree Neck, along 

 shore; Vineyard Haven, on piles; Muskeget 

 Channel, 5 fathoms; Nantucket Harbor, on 

 piles; Great Round Shoal fishing ground, 8 

 fathoms; Crab Ledge, 14 to 20 fathoms (?). 

 Locally, this is believed to be predominantly 

 a shallow water form.

 1912, p. 241. 



Vineyard Sound, 8 to 12 fathoms, common. 

 Verrill. Scattered stations in Vineyard Sound 

 and Buzzards Bay; 3 to 15 fathoms, growing 

 on shells and less commonly on oebbles. 

 Survey. Also recorded from Crab Ledge and 

 Great Round Shoal.

Lepralia serrata Osburn. 



Osburn, 1912, p. 242 (sp. nov.). 



Recorded from a few scattered stations in Vine- 

 yard Sound and Buzzards Bay, 6 to 15 fath- 

 oms; Muskeget Channel, in 7 fathoms; Crab 

 Ledge, in 14 to 20 fathoms; Great Round Shoal 

 fishing ground in 8 fathoms. This species 

 grows on shells, forming at first a rather smooth 

 and later a very rough incrustation. 



Fish Hawk stations: 7521, 7546 bis, 7549, 7726.

Vineyard Sound and Quicks Hole, very abund- 

 ant. Verrill. Dredged by the Survey at 

 scattered stations throughout Vineyard Sound; 

 likewise taken at Crab Ledge, off Sankaty 

 Head, at Great Round Shoal and in Muskeget 

 Channel. For the most part this species occurs 

 incrusting stones and shells, occasionally on 

 algae.

Mucronella pavonella (Alder). 



Osburn, 1912, p. 243. 



Several colonies incrusting hydroid stems and 

 stones at Crab Ledge, August 12, 1909. Also

 August 12, 1909, on stones; also recorded from

Vineyard Sound. Verrill. Abundant and 

 almost universally distributed in Vineyard 

 Sound; common, though perhaps less general, 

 in Buzzards Bay. Dredged by the Survey at 

 all depths and on every kind of bottom 

 throughout the region, incrusting shells and 

 stones. Recorded, also, from Woods Hole 

 Harbor, on piles; Great Pond; Nobska Point 

 and beach; shore of No Mans Land. 

 Fish Hawk stations: 7522 (?), 7523, 7524 bis, 

 7525 bis, 7528 (?) (on stones), 7530 bis, 7533 

 bis, 7534, 7535 (on shells and stones), 7536 bis,

 7541 (?) (on stone), 7541 bis (?), 7543 (on shell 

 of Modiolus}, 7544 bis, 7545 bis, 7546 bis, 7547 

 bis, 7549 bis, 7550 (on Thuiaria and Euden- 

 drium), 7551 (on Clidiophora), 7551 bis (?), 7552

a Dr. Osburn is unable to regard the Escharina porosa of Verrill as being specifically distinct from Lepralia pertusa (Esper).
