light, and the species is small and not readily visible under even slightly unfavorable condi-

 lacking collections. 



Meristic data for L. laurae from the eastern Pacific Ocean are arranged in four geographi- 

 cal units (Table 15). The northernmost group is divided into two units, one from Guadalupe 

 Island, Mexico, the other from collections made elsewhere north of about 21° N (Fig. 66); this 

 division was made as the specimens from Guadalupe Island (31 in 7 collections) were all taken 

 in upwelled water close to shore while the vessels were at anchor, a circumstance suggesting 

 endemism. A fifth group comprises data from Becker (1964a) for specimens designated as L. 

 rara, from the west-central Pacific and southern tropical Indian Oceans.
