Genus SPIO Fabricius 

 Spio filicornls (O. F. Muller) 



Mcintosh, 1910, pp. 172-176, pi. 98, fig. 11, pi. 97, fig. 9, pi. 105, fig. 13; 

 Berkeley, 1936, pp. 475-476; Okuda, 1937, pp. 224-225, figs. 5a-e, 

 Several specimens have been collected from low tidal pools at Marine 

 View, San Mateo County. This species inhabits sandy beaches, where 

 overgrown with some vegetation, at low-water line. Its distribution is 

 cosmopolitan. 



Genus LAONIGE Malmgren 

 Laonice cirrata (Sars) 



Berkeley, 1936; Hartman, 1936a. 



Aricidea data Tread well, 1902, p. 202, figs. 58-60. 



Spionides japonicus Moore, 1907, pp. 204-206, pi. 16, figs. 31-34. 



Spionides foliata Moore, 1923, pp. 182-183. 



? Spionides sacculata Moore, 1923, pp. 184-185. 



This has been obtained in shallow dredgings from off La Jolla, off 

 Half Moon Bay (collected by Dr. T. H. Bullock), and off southern Cali- 

 fornia (collected by the Velero III, Allan Hancock Foundation). In the 

 specimens from La Jolla the first hooks are present ( 1 ) in the last 

 branchial segment, (2) in the last 3 branchial segments, and (3) in the 

 first postbranchial segment, indicating a certain amount of variation in 

 this respect. In other specimens the variation falls within the limits men- 

 tioned above. In all examined, the dorsal transverse fold reaches only a 

 short distance from the dorsal face of the notopodium to the trunk region. 



Two species of Laonice (as Spionides) have been described from Cali- 

 fornia — S. foliata and S. sacculata by Moore (1923). These were sep- 

 arated as follows :
