JOUKNAL OF ENTOMOLOGY AND ZOOLOGY 



of the Biological part of Pomona College, and the plan for special 

 work inclucies a sur\'ey of the whole region from the mountains to 

 the sea. With this in mind, many explorations have been begun, 

 and the aid of specialists in various fiekls is sought, so that 

 we may first of all know the living forms that inhabit this varied 

 and interesting section of California. We hope that a better knowl- 

 edge of the species in the different groups here may lead to more 

 extensive observations both by advanced students from the College 

 and bv others. 



THREE ARCHES BELOW LAGUNA 



Together with the special and general work of the students, col- 

 lections of marine and land animals were obtained all through the 

 summer. Some of these were for the local collection, others to aid 

 in the Avork of the survey. Among the collections made were many 

 species of sponges, hydroids, polyzoans, pycnogonids, marine 

 worms, Crustacea of several groups and, in fact, nearly all the shore 

 forms that could be obtained between tides or a short distance from 

 shore with a small boat. There were also extensiv^e collections of 

 insects and spiders from the hills and from up and down the coast.
