and Mayer's D. sp. may represent intergrades between the two 

 genera. Since the mandibular palp of D. mayeri is not reduced in 

 size as it is in Paracaprella, I have chosen to leave this species in 

 Deutella, although its position is questionable. 



If D. mayeri and Mayer's D. sp. are disregarded because of their 

 apparent divergence from the other species of Deutella, then Luconacia 

 and Deutella are separated geographically, Luconacia being restricted 

 to the Atlantic and Deutella to the Pacific,

Reriarks. — This species was originally described by Mayer from 

 Cape Mendocino, Calif, and later reported from Monterey Bay by 

 Dougherty and Steinberg. Steinberg and Dougherty (1957) reported 

 it as occurring at ". . . probably Port Aransas, Texas." The material 

 they examined undoubtedly belongs to D. californica; however, no 

 additional material of this species has been collected in the western 

 North Atlantic, and it is probable that this species is not a member 

 of the caprellid fauna of that area. 



D. californica can be distinguished from D. mayeri by its 1-x-l 

 setal formula for the terminal article of the mandibular palp, the 

 5-toothed lacinia mobilis on the right mandible, and the single dorsal 

 cephaUc spine. For a description and figures of this species, consult 

 Steinberg and Dougherty (1957).

Diagnosis. — Body without spines. 



Description. — Body smooth, anterolateral margin of pereonite 2 

 with triangular projection. Length of largest male 4 mm, female 3 

 mm. 



Mandible with 3-segmented palp, 1 or 2 setae on terminal article, 

 penultimate article with single distal setae. Left mandible with 5- 

 toothed incisor, 5-toothed lacinia mobilis, setal row of 3 serrate setae. 

 Right mandible with 5-toothed incisor, apically serrate lacinia mobilis, 

 setal row of 2 serrate setae. Palp of maxilla 1 with 3 or 4 apical spines 

 and several setae, outer lobe with 4 or 5 apical spines. Inner lobe of 

 maxiUa 2 with 4 or 5 apical setae, outer lobe with 5 or 6 apical setae.
