204 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 21 



Melpomene Cove, at the south end, to Barracks Beach, at the northeast 

 end of the island, and from shore to 45 fathoms. Seventeen specimens 

 from six stations were collected by C. L. Hubbs. 



Remarks: The proposed new species differs from Pugettia dalli prin- 

 cipally in the shape of the postorbital spine, but also in the less sharply 

 lamelliform cheliped and manus, the reduced lobe on the basal antennal 

 article, and the spinulous, rather than capitate, projections on the ptery- 

 gostomian region. It may be considered either as approaching more 

 closely to P. richi, or as preserving in the adult the transitory appear- 

 ance of the young of P. dalli. It is of interest to note that neither of 

 these species occurs at Guadalupe Island, which is of volcanic origin and 

 oceanic rather than continental in character. 



I take pleasure in naming this distinctive small kelp crab for Dr. 

 Carl L. Hubbs of the Scripps Institution of Oceanography, La Jolla, 

 through whose prolific activities the collections of the Allan Hancock 

 Foundation have been enriched on numerous occasions.

 text-figs. 68, 69. 



Type: Ovigerous female, holotype, U.S.N.M. No. 50286, length 

 along midline 16.7 mm, rostral horns 4.4 mm, width excluding spines 

 13.2 mm. 



Type locality: Five miles off Newport Beach, California; Anton 

 Dohrn. 



Localities subsequently reported, with collectors: California: off east 

 end of Santa Catalina Island, 30 fathoms, Anton Dohrn (Rathbun, 

 1925). Lower California, Mexico: Cortez Bank, 10-16 fathoms, Agassiz, 

 and off Magdalena Bay, 36 fathoms, Albatross (Rathbun, 1925). 



Atlantic analogue: None. A southern California-west coast of Lower 

 California endemic species. 



Diagnosis: Carapace tuberculate and spinulous dorsally, as well as 

 on subhepatic, subbranchial, and pterygostomian regions. Hepatic spine 

 larger than branchial, a second smaller hepatic spine visible between it 

 and the postorbital at a slightly lower level. Rostral horns long, acute, 

 divergent. Basal antennal article with a terminal and a lateral spine. 

 Legs long and sparsely hairy; merus and carpus of chelipeds with spines 

 in rows. Male first pleopod with two lobate projections opposing thick- 

 ened, blunt tip ; intervening lobule not erect nor pinched.
