Another marked feature of his writings is the cataloguing of all 



O o 



known species of certain genera, often with synonymic and o-eoTaph- 

 ical distribution appended. Among the genera thus treated are 

 Cancellaria, Conns, Holospira, Hijhicystis, Lyria, Merce, Opis- 

 thnstoma, ParmacrUa, Pirfin, Placobranchus, Plenrotomaria 

 Pomatias, Eapa, P>,hod?.a, ff/.seUa and Volnta. 



It naturally befel one who had the handling of vast masses of ma- 

 terial to found new genera, as well as innumerable new species, yet he 

 was no sympathizer with the "splitting" school, and discountenanced, 

 rather by example than rebuke, the folly of those who reduce the sci- 

 ence to confusion by manufacturing a new species for every second 

 specimen. To Crosse are due, either singly or in conjunction with P. 

 Fischer, the following, amongst other genera : Acropd/chia, P>erend- 

 tia, Diplomplialus, Eucalodiuw. (reo&iilhi'i. Guextieria. Perei-

PRELIMINARY DESCRIPTION OF A NEW VARIETY OF HALIOTIS 



BY ROBERT E. ('. STEAKNS. 



Haliotisfulgens, Phil , var Walallensis, Stearns. 



On the coast of Mendocino county, California, in the extreme south- 

 west corner, close to the northerly boundary line of Sonoma county, is 

 an embarcadero or shipping point of the lumber interests of that neigh- 

 borhood; here is situated a small settlement known as Gualalla.* The 

 coast hereabout is broken and rocky, with bluffs fifty to a hundred feet 

 high. In the immediate vicinity of this village Mr. J. J. Rivers 

 some years ago collected the forms herein described, specimens of which 

 are contained in the National Museum (No. 98,327) and in the mu- 

 seum of the University of California. The examples in the National 

 collection were kindly presented to me by Mr. Rivers, and are a part 

 of the original lot. The largest adult is of much smaller size than the 

 average adult examples of the ordinary form of H. fulgcns ; my ex- 

 amination of the entire series collected by Mr. Rivers su<;ested the 



v OO 



European H. tuberrulata of the Channel islands. There is a Japa-'' 

 nese figure in Reeve's Conch. Icon., H. planata, which it somewhat 

 resembles. As my note book containing the diagnosis, etc., of the 

 above was unfortunately destroyed some years ago, I am indebted to 



'' Guallala, which is the official pnst office name of the village, is a local- 

 ized corruption of the Indian Walalln^ which latlei, I think, stnuld be per 

 petuated .
