dredged in 45 fathoms, in the Bay of Panama, is especially inter- 

 esting, being one of the Crustaceans found in the waters on both 

 sides of the Isthmus that has not undergone changes since its 

 elevation. 



Calcinu^ elegans (H. Milne Edwards) is recorded from the 

 Carolines for the first time, where an unusually fine series, in- 

 cluding the various growth stages of the species, was obtained 

 by the "Ara." 



Paguru^ cataphractus Boone, a new species of hermit, from 

 Lahaina, Maui, Hawaii, is described and deposited in the increas- 

 ing type series of the Vanderbilt Marine Museum. A second 

 member of this genus, P. deformis H. M. Edwards, was taken in 

 Zamboanga and appears to be the first Philippine material of 

 this species deposited in any American Museum. The rare P. 

 varipes Heller was also taken by the "Ara" at Lahaina, a record 

 which very substantially extends the known range of this species 

 from the Malay Archipelago to Hawaii. 



The catch of over a hundred and forty specimens of the scarlet 

 Munida gregaria (Fabricius) at several Chilean stations, from 

 Ton Gay Peninsula to the Chiloe Archipelago, provided material 

 sufficient to evaluate the variation existent between the different 

 growth stages of the species, where much confusion has been. 



Likewise, examination of the series of little Porcellanid crabs 

 from the Chiloe Archipelago directed attention to the fact that 

 these specimens of the "Alva" South American Expedition of 

 1935 are identical with M. Guerin de Meneville's type of PorceU 

 lana granulosa from Valparaiso, as described by him a hundred 

 years ago, and enabled the writer to restore this name which 

 automatically has priority over the several synonyms under which 

 the species is better known. 



The Cirripedia described include three species, the circum- 

 tropical pelagic Lepas anserifera Linne found floating in the 

 Indian Ocean, attached to the "pen" of a very rare Cephalopod 

 mollusk and two deep-water barnacles, each of which was taken 

 attached respectively to rare sea-urchin's spine, Cidaris abyssi- 

 colu (A. Agassiz) , f rom off Sand Key Light, Florida, in 65 to 100 

 fathoms, and a rare spider crab, Rochinia crassa (A. Milne Ed- 

 wards), from off Fowey Rocks, Florida, in 100 to 200 fathoms, 

 both of which species are illustrated.
