Something over fifteen years ago Dr. Kendall was informed by a 

 Georges Bank fisherman that occasionally flounders were taken on 

 Georges Banks that were known to the fishermen as "lemon sole," 

 owing to their prevailing yellow coloration. The identity of this fish 

 was never definitely determined. The U. S. National Museum a num- 

 ber of years ago received from Fulton Market, New York, some large 

 flounders taken in deep water off the New England coast which were 

 then regarded as a deep-water form of P. americanus. The fish is thick 

 and firm-meated, the flesh flaky and, when cooked, moist and of deli- 

 cious flavor. Ethel M. Smith. 



ZOOLOGY. — The Bryozoa of the Woods Hole region. Raymond C. 

 Osburn. Bulletin of the U. S. Bureau of Fisheries, vol. 30, 1910, 

 pp. 203-266, pis. xviii-xxxi. Issued June 25, 1912. 



The biological survey of the waters of Woods Hole, Mass., and vicin- 

 ity, covering the years 1903 to 1909 arid to be reported upon in a forth- 

 coming extensive volume of the Bulletin of the Bureau of Fisheries, fur- 

 nished so much bryozoan material that Dr. Osburn was led to prepare a 

 special systematic discussion of this group. The region embraced in the 

 survey includes Vineyard Sound between a line drawn from East Chop 

 to Falmouth Heights and one from Gay Head to Sow* and Pigs Reef, 

 and Buzzards Bay above a line drawn from Sow and Pigs Reef to the 

 Hen and Chickens Lightship. 



In consequence of the fact that the Bryozoa of the American Atlan- 

 tic coast have received comparatively little study, the collections of the 

 recent survey have nearly doubled the number of known species from this 

 region, bringing it up to 81, besides adding a number of varieties which 

 have at times been classed as species. Only 5 of these species, however, 

 are described as new, with 7 others known to occur only within this 

 intermediate region between Florida and Canada. Of characteristic 

 southern species there are almost no representatives. Fully one-half 

 are characteristically northern or even arctic in their range. Another 

 fourth is composed of species which have such wide distribution that 

 they may be called cosmopolitan. 



Within the region itself, 28 species found in the outer waters are not 

 represented in the inner waters, and 12 species from the latter areas are 

 not found in the others. This leaves more than one-half of the total 

 number common to both inner and outer waters. Comparatively few 

 of the species show a preference for any special habitat, and the majority
