PART 1 GARTH : PACIFIC OXYRHYNCHA 121 



3.7 mm, second, third, and fourth legs 18.8, 17.3, and 13.0 mm, 

 respectively. Female paratype: length 12.3 mm, width 7.6 mm. 



Color in life: Deep olive buff. (Petersen) 



Habitat: Sandy bottom, associated at times with rock, mud, shell, 

 nullipore, and coral. 



Depth: 20-80 fathoms. Collected once intertidally. 



Breeding: Ovigerous females ranging in size from 7.2 mm to 10.0 

 mm were obtained in the months of December and January. 



Remarks: Caution must be excercised with respect to the first of 

 the key characters given, that of the bifid rostrum; for experience has 

 shown that several species of Podochela, notably P. latimanus when 

 young and P. veleronis as adults, exhibit this character. With two 

 median tubercles on the first abdominal segment, P. schmitti is most 

 closely related to P. lobifrons ( = P. barbarensis) of southern Cali- 

 fornia, northern Lower California, and the Gulf of California. The 

 best criteria for distinguishing one from the other are the ultimate 

 length of the rostral spine, which in mature P. lobifrons may attain 

 half or three-fifths the postrostral length of the carapace, and the shape 

 of the hepatic and pterygostomian spines, which are compressed or 

 strap-shaped in P. lobifrons but perfectly cylindrical in P. schmitti. 

 This separation from P. lobifrons is a more important one than the 

 distinction from P. hemphilli made in the original description (Garth, 

 1939, p. 13), for it is P. angnlata, rather than P. schmitti, which com- 

 plements P. hemphilli in equatorial latitudes.
