THE NAUTILUS. 15 



He very kindly notified me and gave a Sunday to a trip to 

 Cohasset where I saw the remarkable haul still alive. The early 

 darkness of a November afternoon, the absence of apparatus and 

 books and my absorption in professional work which precluded the 

 possibility of my attempting to transport and preserve the living 

 creatures for further study, may be held sufficient excuse for my 

 failure to identify the species at the time fully and reliably, but not 

 for my apparent failure to preserve some of the more interesting 

 forms for later working over. To my great regret, however, the 

 single Dorid form is the only one I am now able to find. 



The species identified were as follows according to my notes: 

 Cratena gymnota (Couth.). " 1 specimen quite juv., cores of cerata 



very dark." 

 ? Crateiia veromcae Verrill. " 1 specimen, abt. | in., cerata very 



green, very like viridis A. & H." * 

 Coryphe/la mananensis (Stimps.) " 1 specimen, abt. i in., juv." 

 ? Coryphella salmonacea (Couth.). " > diversa Couth., 1 nearly 

 adult spec, abt, 1 in." Unfortunately salmonacea (Couth.,) 

 [now Bergh] does not include diversa (Couth.), as I then sup- 

 posed, and both species are in utmost need of further elucidation. 

 Wherefore I much regret my failure to preserve this specimen 

 as a consequence of which I am now quite unable to say what I 

 really had before me — at all events something wholly distinct 

 from mananensis. 

 Dendro7iotns fro7idosns (Ascanius). " 3 specimens, abt. 1 in." 

 Dendronotus rohustus Verrill. " 1 specimen, abt. ^ in." 

 Polio hssonii (d'Orb.) " 2 specimens, abt. ^ in., like A. & H's. 

 figures of adult but anal tubercles very conspicuous and white 

 instead of yellow." 

 LamelUdoris aspei'a (A. & H.) ^pallida A. Ag. " 1 specimen, 

 juv., abt. ^ in." 

 The above enumeration certainly includes all the species (and like- 

 wise all the specimens) of all except the Aeolid forms. But of the 

 Aeolid species enumerated there were in all likelihood many more 

 specimens, while I noted that there were at least three obviously 

 different Aeolid species which I did not undertake to name. 

 Quite probably there were more. The whole enumeration only 



* I had Alder & Hancock's figure before me in making the comparison.
