hon diazi and T. lorenzoensis Durham,

ies are described as new in an appendix. ree species 
rs Ob Les confidently be assigned to a subfamily are discussed 
and figured, and 38 are merely listed by name because of lack of 
sufficient documentation. [Ironically while this book was in press, 
a name-change was published that affects one type species: Bullock 
(Tulane Univ. Studies in Geology, vol. 12, p. 133, Sept. 1976) shows 
that an earlier name for the type of Attiliosa is Peristernia nodu- 
losa A. Adams, 1855,] 
A glossary, with illustrated terminology, a list of sources for the 
figures, a bibliography, and an index complete the work. The book 
is assembled with the care for which Stanford Press has become noted, 
and it forms a worthy setting for the elegant drawings of Anthony 
D'Attilio, who combines his ability as artist with his interest in 
shells to our advantage. David Mulliner's skill as photographer 
comes through well in the color plates. The book is, then, one that 
can be displayed with pride.

(The authors were pleased to present the shell photographs in actual 
size. However, we have received comments on the loss of detail in 
small species -- especially those of 5mm or less -- that are also 
reproduced life-size on the color plates. mkj) 

ARTICLE OF THE MONTH 
In Sarsia 60: 25-40, 1976 is an article by Dr. Tor Stroémgren entitled 
"Growth patterns of Mytilus edulis in relation to individual varia- 
tion, light conditions, feeding, and starvation." The author points 
out that shells were measured once or twice daily by laser diffrac- 
tion and that growth was considerably higher in animals kept in the 
dark, but that animals grown under normal conditions of day and night 
showed greater growth during the day. It is Suggested that a minimum 
period of darkness is necessary to give rapid growth. All specimens 
responded to starvation within 24-36 hours by reduced growth rates, 
regardless of previous feeding.
