Remarks. — The Barrington Island and Charles Island specimens were 

 compared with the type female, USNM No. 21585, and agree so closely 

 that the name is applied without hesitation to Galapagos specimens. The 

 female type is more ornamented throughout, the ornamentation consist- 

 ing of a more spinulous orbit with a definite outer, as well as inner, notch. 

 In the type specimen the third anterolateral tooth appears more promi- 

 nent; in Hancock specimens, the fourth. The remainder of the Albatross 

 specimens exhibit sufficient latitude in variation to encompass these slight 

 discrepancies. 



L. maculatus is now recorded from the Galapagos Islands.
