P. Brylski 1981 Journal Vicente Costa Junction, Inyo Co., Calif. (Sept cont'd) The rocky-scrub habitat yielded the following species: P. crinitus 10 (all released) Perognathus formosus 1 (live) P. longimembris 1 (in alcohol) D. merriami 3 (released) D. microps 2 ( " ) 17 captures/25 traps Again, most animals were fixed in 10% formalin. Since I've already captured a number of merriami's, (and Peromyscus), there were released. Also, since I need to break camp and head to Walker Pass, the fewer animals to groom, the better. My plan for catching deserti didn't work. They certainly aren't numerous here -- but there's certainly more than one. The sand isn't loose or deep enough (or both) here. The valley winds scour the flats leaving a fine pavement of sorts -- not the typical deserti pavement however. Weights & total body length of merriam k-rats are: 220/36.5; 250/39.5; 240/33.5; 250/34; 240/39.5; 215/34.5 235/35; 246/36; 245/36. The circled individuals are probably this year's juveniles. Apparently they reach adult weight prior to adult body length (?) We know that adult proportions are reached a month or so after parturition -- this places the event in early July or later. Wait! The first individual had a broken tail. The second may have escaped my notice
