Types: The holotypo, an ovigerous female, tJSNM 101730, 

 obtained in "burrow water" (see p. 160), C.6, April 0, 1958; it has been 

 dissected. The allotype male, USNM 101731, from which figures 

 6, e-i, and 7 were drawn, was found in washings from a Callianassa cali- 

 jorniensis collected at the same place, February 11, 1956. Paratypcs 

 from several localities have also been deposited in the U.S. National 

 Museum, Nos. 101371-101378. 



Other material examined: From "burrow water": C.6: 6 females, 

 11 males, 7 juveniles, February 2, 1958. 11 females, 7 males, 1 juve- 

 nile, April 6, 1958. C.7a: 1 male, February 3, 1958. C.7b: 4 

 females, 1 juvenile, February 3, 1958. 



From washings of Callianassa calif omiensis: C.3: 2 females, 1 mi 

 from 6 of 19 hosts. C.6: 1 female, 1 juvenile from 2 of 12 hosts, 

 February 11, 1956. 1 male from 1 of 6 hosts, February 25, I! 

 1 female from 1 of 4 hosts, March 16, 1956. 2 females from 1 of 12 

 hosts, February 2, 1958. CIO: 2 females from 40 hosts; figure 6a 

 is based on one and figures 5 and 66 r/ on the other. C.l 1 : i female. 



Description of the female: As that for adhaerens (p. 177), 

 except for the following characters. Body 2.08 mm. (mean of 7 speci- 

 mens, range 1.97-2.24 mm.) in length; width of prosome 0.91 mm. 

 (0.74-1.2 mm.). Inner dorsolateral seta on caudal rami rather longer 

 in proportion to the others. Armature and ornamentation of append- 

 ages in general more strongly developed. Denticles on labium much 

 stronger and more widely spaced; arranged in 2 deep crescents, one 

 on either side of midline. Mandible with a rudimentary second seta. 

 Ventral spine on terminal segment of maxilliped with 3-5 denticles on 

 antcroventral side. Terminal spine on fifth legs proportionately 

 smaller; setae on both podomeres longer: specifically, seta on 

 terminal segment longer than terminal spine. Ornamentation of 

 distal segment stronger and more extensive. Color iu life verj 

 similar to that of thysanotus. 



Description of the male: Size of body, unlike condition in 

 thysanotus, more or less equaling that of female: 2.05 mm. (mean of 

 7 specimens, range 1.9-2.3 mm.) long, width of prosome 0.8 mm. 

 (0.77-0.84 mm.). General appearance very similar. »Spermatophores 

 attached to genital segment of female all flattened but, when iu body 

 of male, like those of thysanotus.
