is shown in the following table, and in having the meropodite of 

 the third pair thicker: 



A female is especially like S. goodei in possessing a rndiment of 

 an antennal .scale, a stylocerite longer than the basal antennular ar- 

 ticle, the meropoclites of the third pair more similar to those of the 

 female of S. goodei (proportion 3.4), and lastly 12 spines on the outer 

 uropod, as in the male of the last-named species. I propose to desig- 

 nate the example from the Pacific under the name of S. goodei occi- 

 dentalism remarking that the female last described would probably be 

 found to be more distinct in a more extended series. 



Named for the late Dr. George Brown Goode, Assistant Secretary 

 in Charge of the United States National Museum.
