NO. 13 coe: revision of the nemertean fauna 257 



8. Carinomella lactea Coe, 1905 



Habitat. In sand between tides. 



Distribution. At present known only from Monterey, San Pedro, and 

 San Diego, California. 



Family Carinomidae 



Genus GARINOMA Oudemans 

 Only a single species has been found on the Pacific coast. 



9. Garinoma mutabilis Griffin, 1898 

 (Plate 25, figs. 21, 22) 



C. griffini Coe, 1901 ; C. mutabilis Coe, 1905. 



Habitat. In sand, sandy mud, and clay between tides and below. 



Distribution. British Columbia, Puget Sound, and southward to Gulf 

 of California. (Angeles Bay, Mexico, Hancock Exped.) 



Reproduction. During the summer months eggs are sometimes depos- 

 ited within a few hours after the worms have been collected and placed 

 in clean sea water. Usually, however, it is necessaiy to obtain a supply for 

 enibi-yological study by cutting the female lengthwise. Sperm may be 

 added from a ripe male. Development of the direct type proceeds rapidly.
