We identified a specimen provided by him as L. 

 inquilinus . Since that initial occurrence he has 

 collected several other Liparis, which are proba- 

 bly also L. inquilinus , from bay scallops (pers. 

 corarann.) . Liparis inquilinus originally collected 

 from sea scallops were placed in aquaria with bay 

 scallops to determine if they would attempt to 

 enter the scallops. These scallops were completely 

 ignored and the fish made no attempt to enter or 



attach to them. When brushed by L. inquilinus, 

 the bay scallops either showed no response or 

 closed the valves slightly. Bay scallops are found 

 in much shallower water than the sea scallops, 

 and the occurrence of L. inquilinus in depths fre- 

 quented by bay scallops is unusual. These fish 

 which occur in shallower water may attempt to 

 associate with bay scallops in the absence of their 

 regular host. Confusion in host recognition may
